Hello,

My solution is too complicated, the assign() is not needed.


lapply( ls()[grep("^x\\.[[:digit:]]+$", ls())], get)


Hope this helps,

Hello,

Try the following.

x.1 <- 1:3
y.1 <- 1:4
x.2 <- 5:10


vecs <- ls()[grep("^x\\.[[:digit:]]+$", ls())]
lapply(vecs, function(.x) assign(.x, get(.x)))


Then you can use vecs to attribute names() to the result.

Hope this helps,

Dear R People

I have a simple list question, please:

I have vectors x.1, x.2,...x.n (each of different lengths) and I

would

like to combine them into a list.

However, I'm sure that there is a better way to do this than to type
in x <- list(x.1,x.2,x.3,...)


Is there a better way to do this, please?  I was thinking about
possibly using grep?

Thanks,
Sincerely,
Erin
