As Dan Davison said, the more standard R way would be to put all your
data frames in a list, then iterate over the list.
However, if do want to have your data frames in separate variables, and
then get each data frame in a loop similar to the code fragment above,
try something like this:
for (i in 1:(L-1)) {
dataName <- paste("fData.", i, sep="")
df <- get(dataName)
... do something with data frame df ...
}
You can also give additional arguments to get() to tell it where to look
(pos=,envir=), and whether to look in parent environments
(inherits=TRUE/FALSE).
