hi dieter, the method i'm using is in excel, copying the data, then in r
> w<-read.delim("clipboard") > w<-as.data.frame(w) i've been doing a bit more fiddling, and have identified the 'class' of the column that i'm having trouble with, is classified as 'factor' whilst the rest are numeric. if i just change that column to as.numeric of the column, this has appeared to have solved the problem. Has this changed that data at all though? Thanks. Dieter Menne wrote: > > > > Katie2009 wrote: >> >> I'm trying to analyse some excel data in R.
