Hi

It means that what you read is a factor. Most probably the values are formated in scientific notation which is not read properly as numbers. You shall format numbers in your Excel file so that it does not have comma but dot.

Or you can transfer those values to numbers in R.

see
?factor
?as.character
?gsub

And if you are in reading some docs you can try to locate R-intro and go through it. It can help you greatly in beginning.

Petr

Hi

You shall probably use C or similar program for such task.

As I understand you want only odd rows. If yes, this will do it for you

odd<-seq(1,d,2)
datalist<-cd[odd,]

If not please explain better your real intention.

Petr
