one way is the following:
for (i in 1:50) {
dd <- data.frame(x = gl(2, 1), y = rnorm(2))
assign(paste("d", i, sep = ""), dd)
}
However, I would suggest to put all these data.frames in list, e.g.,
df.list <- lapply(1:50, function (i) data.frame(x = gl(2, 1), y = rnorm(2)))
names(df.list) <- paste("d", seq_along(df.list), sep = "")
I hope it helps.
Best,

Dear R users,
I want to creat a group of data frames, such as:
d1<-data.frame(x=factor(),y=numeric(),...)
d2<-data.frame(x=factor(),y=numeric(),...)
d3<-data.frame(x=factor(),y=numeric(),...)
:
:
d50<-data.frame(x=factor(),y=numeric())
How can I use the loop to simply my procedure?
Thanks advance
Ted
