R as.numeric()
Hi,
I have a bit of a problem with as.numeric or as.double.
I read in an excel-file (either xlsx::read.xlsx2 or gdata::read.xls).
Select a subset and then try to make it numeric:
# read in the excel-file
alldata<-read.xlsx2("input.xls",1)
# select the subset
s<-subset(alldata, select=c("cI","cII","cIII","cIV","cV"))
# unluckily
