I’m having trouble with HowTo-flowCore, section 2.2.1.

Trying to create a new flowSet out of directories “mydata1” and “mydata2”:

"C:/Documents and Settings/Owner/Desktop/Data"

> frames<-lapply(dir(list.files("C:/Documents and
Settings/Owner/Desktop/Data/mydata1", "C:/Documents and
Settings/Owner/Desktop/Data/mydata2"), full.names=TRUE), read.FCS)
> as(frames, "flowSet")
Error in names(from) <- paste("V", seq(1, length(from)), sep = "") : 
  'names' attribute [2] must be the same length as the vector [0]

> sessionInfo()
