pheatmap: change text color
如何更改Pheatmap中的文本颜色？我已经尝试了以下操作，但是它不会更改轴的文本和标签，但是不起作用
1 2 | par( col.lab="#FFFFFF", fg="#FFFFFF", col.main="#FFFFFF", col.axis="#FFFFFF", cex.main=2, cex=2) pheatmap(heat_data, cluster_rows = FALSE, gaps_row = c(3), cellwidth=35, cellheight=35, fontsize = 25) |
这是答案。该代码修改了x和y标签的颜色和字体大小以及树状图的颜色和线宽。颜色设置为白色，但是您可以将其更改为其他颜色。
1 2 3 4 5 6 7 8 9 10 11 12 | p = pheatmap(heat_data, cluster_rows=F, gaps_row = 3, cellwidth=45, cellheight=45, fontsize = 20, angle_col ="90", legend=TRUE,legend_breaks=c(40, 20, 0, -20, -40, -60), legend_labels=c(40, 20," 0", -20, -40, -60), annotation_row = NULL, annotation_legend = FALSE, labels_row = NULL, labels_col=NULL, annotation_names_row = F, annotation_names_col = F, annotation_colors = ann_colors, dist="euclidean", col=COLS, scale="none", show_rownames = T, show_colnames = T) my_gtable = p$gtable my_gtable$grobs[[3]]$gp=gpar(col="#ffffff", fontsize=20)# assuming that the xlabels are in the third grob my_gtable$grobs[[4]]$gp=gpar(col="#ffffff", fontsize=20)# assuming that the ylabels are in the fourth grob my_gtable$grobs[[1]]$gp=gpar(col="#ffffff", lwd=2) # change the color of the dendrogram and set the linewidth to 2 my_gtable$grobs[[5]]$gp=gpar(col="#ffffff", fontsize="20", just="center") # legend |
