Changes in version 3.0.0 - Breaking change to smoothing strategy in plot_gene(), plot_region(), and plot_granges() to use weighted moving mean instead of loess. This deprecates the span argument in favour of smoothing_window which is defaulted to 2000 bases. - Smoothing for various plotting functions was previously performed using loess smoothing, this performed locally weighted linear estimation to create a smoothed line, the span argument controlled the proportion of data used in this smoothing. This parameter was difficult to tune because under a fixed span, the smoothed line became flatter as the plot region grew larger. Internally, NanoMethViz dynamically calculated a span that changed inversely proportional to the width of the plotting region, decreasing the span as the plot region grew. However the calculated span was invisible to users, and it unintuitive to users how to set a span to change the appearance of the plot. - Changing the smoothing method to a weighted rolling mean lead to the new smoothing_window argument which represents the window size in bases from which data is used for smoothing around each point. This serves the same purpose as the dynamic calculation done previously, but is set more explicitly and should be more intuitive for users. The default is always 2000, and can be increased to increase smoothness and decreased to decrease smoothness. - Breaking change to the appearance of plot_gene() plots, previously the isoform annotation would be restricted to only the gene of interest. It is now changed to follow the same behaviour as plot_region() whereby all isoforms in the region are plotted. - Breaking change to the default plotting options for plot_region(), plot_gene() and plot_grange() to plot heatmap by default. - Possible breaking change to query_methy(simplify = FALSE), it will now return a list that is the same length as the number of regions queried, where it previously returned nothing if a particular sequence was missing from the tabix. - Added gene_anno argument to plot_region() and plot_granges() to control whether gene annotation is plotted. - Added plot_violin() function for creating violin plots for samples over specific regions. - Added check to remove hard-clipped reads because they may not have matching mod strings. - Changed gene annotation to always put label on visible isoforms, previously labels are plotted at the center of isoform. - Changed the order of columns when querying from ModBam to be the same as when querying from Tabix, with readname at the end instead of being the second column. - Fixed memory leak in bam parsing due to out of bounds access. - Fixed crash when CIGAR doesn't match length of SEQ. Changes in version 2.6.0 - Added preliminary modbam file support. - Changed rug plot to appear under other geoms. This helps with visibility of data when methylation values are close to 0. - Changed heatmap alpha from 0.5 to 1, line width from 1.0 to 1.2 and line colour from black to darkgrey. - Changed x-axis limits on plots to be controlled using coord_cartesian instead of scale_x_continuous. Plots should now accurately represent data around the boundaries. Changes in version 2.4.0 - Fixed plot_region_heatmap() producing the wrong plot when a factor is used for the chromosome. - Fixed nanopolish and f5c import positions being off by 1. - Fixed broken samples() setter for NanoMethResults. - Added plot_agg_genes() function as a shorthand for plot_agg_regions(x, exons_to_genes(exons(x))). - Added the ability to interrupt methy_to_bsseq() calls. - Added handling for NanoMethResults objects in filter_methy(). If NanoMethResult is used as input, then NanoMethResult is invisibly returned as output. - Added black outlines to exons in annotation to distinguish contiguous segments for features like tandem repeats. - Added line_size argument to plot_gene(), plot_region() and plot_granges() plots for adjusting line size. - Added subsample argument to heatmap plots, default 50. This reduces the number of rows shown the plot to the specified amount. - Added get_exons_mm10(), get_exons_hg19(), and get_exons_hg38() as replacements for get_exons_mus_musculus() and get_exons_homo_sapiens(). - Changed heatmaps to no longer plot samples that are absent from sample annotations. - Changed heatmap labels to appear on the right rather than on top. - Changed heatmap alpha from 0.33 to 0.5. - Changed arrows in exon connectors to appear in the middle as open arrow instead of at the end as closed arrow. - Changed default X axis labels to be rescaled to appropriate SI-style. e.g. Kb, Mb, Gb. Changes in version 2.2.0 - Added heatmap argument to plot_gene(), plot_region() and plot_granges(). This adds a read-heatmap to the plot. - Added cluster_regions() function to perform k-means clustering on a table of genomic regions based on methylation profile. - Added median averaging method for trends in plot_gene(), plot_region() and plot_granges(). This can be changed using the new avg_method argument, default is mean. - Added filter_methy() function to create a filtered methylation file. - Added region_methy_stats() to obtain average methylation fractions of specific regions. - Added methy_to_edger() direct conversion wrapper around methy_to_bsseq() and bsseq_to_edger(). - Added palette argument to plot_gene(), plot_region() and plot_granges() to allow custom colour palettes. - Fixed bsseq_to_edger() failing when regions argument was used. - Fixed heatmaps not staying in a single column when more than 2 groups were present. Changes in version 2.0.0 - Major changes to plot_agg_regions(). - Features of plot_agg_regions() and plot_agg_regions_sample_grouped() merged into one interface. - Regions now specified using single table. - Changed plot_regions() default window proportion to 0. - Changed default theme from theme_bw() to theme_tufte(). - Added Megalodon data import instructions to "Importing Data" vignette. - Added scico palette defaults for heatmaps. These are colourblind friendly. - Added check for 0 length queries which would cause program to hang indefinitely. - Added setters for NanoMethResult attributes methy, samples and exons. - Added MDS and PCA plots. - Added vignette for using external annotation and dimensionality reduction. - Added binary thresholding for plot_gene(), plot_region() and plot_agg_regions(). - Added regions argument to bsseq_to_edger() to calculate aggregate counts over features rather than per site. Changes in version 1.1.4 - Added palette argument to aggregate plots - Added exons_to_genes() function to convert exon annotation to gene annotation - Added plot_granges_heatmap() function to use GRanges for plotting heatmaps Changes in version 1.1.3 - Fixed group handling for list region input in plot_agg_regions() - Fixed unused window size argument in plot_region_heatmap() - Fixed error when reads overlap in name and position for internal function StatLM() Changes in version 1.1.2 - Changed example dataset exon annotations from all genomic exons to just those contained in data. - Fixed methylation heatmap to no longer be hard coded for Peg3. - Added plot_region_heatmap() as analogue to plot_region(). - Fixed plot_agg_regions_sample_grouped() to use group column of NanoMethViz::samples(x) rather than haplotype. - Added unit tests. Changes in version 1.1.1 - Added methylation heatmap via plot_gene_heatmap(). - Fixed gene_anno() in plot_gene() for argument so FALSE actually turns off gene annotation. - Added warning for cpp11 versions <0.2.5 which may cause memory crashes when trying to import methylation data. - Added cpp11 version dependency to address tidyverse/readr#1145. - Added query methylation by gene using query_methy_gene(). Changes in version 1.0.0 - Initial Bioconductor release.
