Hi, thanks for the amazing tool.

My sample names are a bit long, how can I rotate to 45degrees the sample names?

cheers.

Hi, and thanks for your question. The plots produced by coseq are actually made with ggplot2, so you can modify them as you wish with standard ggplot2 code. Here's an example to change the sample labels on cluster boxplots and rotate to 45 degrees.

## Quick simulation
library(coseq)
countmat <- matrix(runif(300*4, min=0, max=500), nrow=300, ncol=4)
countmat <- countmat[which(rowSums(countmat) > 0),]
sample_labels <- paste0("Super long name for replicate ", 1:ncol(countmat))
run_arcsin <- coseq(object=countmat, K=2:4, iter=5, transformation="arcsin",
                    model="Normal", seed=12345)

## Customize coseq boxplots
library(ggplot2)
plot(run_arcsin, graph="boxplots")$boxplots +
  scale_x_discrete(labels= sample_labels) +
  xlab("") +
  theme(axis.text.x=element_text(angle=45, vjust=1, hjust=1))

Best wishes, AR
