Hi,
Try this:
dat1<-read.table(text="
id date a b c y
1 1 8/6/2008 Red 15 B 22
2 1 8/6/2008 Green 15 B 22
",sep="",header=TRUE)
dat1$date<-with(dat1,as.factor(date))
dat1
id date a b c y
1 1 8/6/2008 Red 15 B 22
2 1 8/6/2008 Green 15 B 22
is.factor(dat1$date)
[1] TRUE
A.K.

Subject: [R] convert date to a factor
Hello,
I would like to convert date as a factor to represent time in a repeated
measure situation in the following code. How would I do that?
> d <- read.csv(file.path(dataDir,"data.csv"), as.is=T,stringsAsFactors =
FALSE)
> d[1:2,]
id date a b c y
1 1 8/6/2008 Red 15 B 22
2 1 8/6/2008 Green 15 B 22
Thank you,
Y
