Within lapply load the file and return the value of the thing or
things in the file you want. Something like this:
 "x1.RData" "x2.RData" "x3.RData" "x4.RData"
Each of my files contains a single number stored in an object called
'x'. Within the loop 'x' has the value just loaded from the file.
Another method is to use the environment argument of load to save into
an environment other than the global one...
