Identify and cbind multiple vectors based on vector name

问题

I have 100 numeric vectors named sim1 to sim100 in my workspace, all of the same length (18). I'm trying to find a way to identify them and cbind them to create a data frame of 18 rows and 100 columns. I can easily create a character vector of length 100 that contains the names of the vectors:

myvector<-ls()
myvector<-[grep("sim",myvector)]

..but I'm stuck on how to create a list of the objects themselves that I assume I could then use with do.call. Any suggestions please?

回答1:

You can try

 do.call(cbind.data.frame, mget(paste0('sim', 1:100)))

Or as @Frank mentioned in the comments

 data.frame(mget(paste0('sim', 1:100)))
