用pheatmap函数在Linux系统上画图
输入数据格式：如下
p2=pheatmap(marker,cluster_cols = T,cluster_rows = T,clustering_distance_rows = "correlation",scale = 'column',colorRampPalette(colors = c("blue","white","red"))(100),treeheight_row = 20,treeheight_col = 20,cellwidth = 15,cellheight =15,border_color = 'white',fontsize = 15,legend_labels = 'scale.avg_logFC',legend = T)
结果出现了如下error：
Error in .External2(C_X11, d$display, d$width, d$height, d$pointsize, : ,border_color = 'white',fontsize = 15,legend_labels = 'scale.avg_logFC',legend = T）无法打开X11cairo设备
这里只需要补充一个参数就行：silent = T，函数默认silent=F,参数解释如下：
do not draw the plot (useful when using the gtable output)，而我们使用xshell连接服务器时，无法实现画图，故出现error，把silent改成T，让它不画图，就可以啦，正常出出图用ggsave保存就可以啦
