Loop on vector name
Thanks for this mail. It runs perfectly, but now I stuck on how to convert the result in a vector format for further matrix-compputation. e.g. How to convert "sapply(lis, sd)" to vector?

you need to get(), e.g., try this:
dat1 <- rnorm(5)
dat2 <- rnorm(6)
dat3 <- rnorm(7)
lis <- lapply(paste("dat", 1:3, sep =
""), get)
lis
sapply(lis, sd)
I hope it helps.
Best,

I have 3 vectors with object name : dat1, dat2, dat3
Now I want to create a loop, like :
for (i in 1:3)
{
cat(sd(dati))
}
How I can do this in R?
