R help - Jan 2010 - question about reshape

Hello everyone,
 I have a bit of a problem with reshape function in R.
 I have simulated some normal data, which I have saved in 4 vectors.
 y.1,y.2,y.3,y.4 which I combined a dataset:
dataset<cbind(y1,y2,y3,y4). I have also generated some subject id number,
and denoted that by subject.
 So, my dataset looks like this:
    subject       y.1        y.2       y.3       y.4
 [1,]       1 20.302707 16.9643106 30.291031  7.118748
 [2,]       2  9.942679  9.3674844  7.578465 16.494813
......etc, I have 20 subjects.
 I want to transform this data into long form dataset, but it does not work.
 I am using reshape command, and should be very straight forward...
 Here is what I use:
 long<-reshape(dataset, idvar="subject",
v.names="response",
varying=list(2:5), direction="long")

Here is what I get:
Error in d[, timevar] <- times[1L] : subscript out of bounds

Now, do I get that error because the first column shows me the row number?
 I have been using R for a while, but not a lot for data manipulations.
 Any help would be great! Thank you in advance.

Try this:

ong<-reshape(as.data.frame(dataset), idvar="subject",
v.names="response", varying=list(2:5), direction="long")
or
dataset <- cbind.data.frame(y1, y2, y3, y4)
