Creating data frames dynamically using items of loop in R

I have a for loop as

for(i in c("a","b","c","d"))
{
    as.name(paste("df",i,sep=""))= mydataframe
}

mydataframe is a data frame and I want to create data frames dfa,dfb,dfc and dfd using this loop.

The as.name(paste("df",i,sep="")) does not work here. I do not want to create a list that has the 4 data frames.

Can I directly create 4 data frames from this loop?

You can do this using assign. Although in general, you are better off using lists.

Using your example:

for(i in letters[1:4]){
  assign(paste0("df", i), mydataframe)
}

Note that this will simply create the same object 4 times, unless you change what mydataframe is inside the loop.
