Hello edgeR maintainers,
I just ran into an error with code that is several weeks old. I cannot
subset my DEGList object anymore. I created it from the HTseq output:
> files <- list.files("Gene_counts",
recursive = FALSE, pattern = "counts",
full.names=TRUE)
> rc <- readDGE(files, labels = labels)
> dim(rc)
[1] 23429 40
> out1 <- which(colnames(rc) == "PGE_old_E")
> rc <- rc[,-out1]
Error in `$<-.data.frame`(`*tmp*`, "group", value = integer(0)) :
replacement has 0 rows, data has 39
Subsetting on genes works:
> test <- rc[1,]
But subsetting on samples does not:
> test <- rc[,1]
Error in `$<-.data.frame`(`*tmp*`, "group", value = integer(0)) :
replacement has 0 rows, data has 1
The code worked a couple of weeks ago. I guess that there is a bug in
the latest edgeR version that is causing this? Interestingly, I cannot
reproduce the error using the example data in the DGEList manual:
y <- matrix(rnbinom(10000,mu=5,size=2),ncol=4)
d <- DGEList(counts=y, group=rep(1:2,each=2))
I would be grateful for any help!
Cheers,
Katja
