...ment. One way around this would be to do the replacement only for closures that have the same environment as the package environment. Basically change the relevant lines in envir.c (do_libfixup) with - while (p != R_NilValue) { if (TYPEOF(CAR(p)) == CLOSXP && CLOENV(CAR(p)) != lib) SET_CLOENV(CAR(p), env); p = CDR(p); } In case any one wonders, I know I could wrap the function in a list and call the function with foo[[1]]() - but it really does not look very natural. Closures are often so useful that it is desirable that they can be used from libraries. Can someone comment wheth...

Currently, I load the RData file then ls() and str(). But loading the file takes too long if the file is big. Most of the time, I only interested what the variables are in the the file and the attributes of the variables (like if it is a data.frame, matrix, what are the colnames/rownames, etc.) I'm wondering if there is any facility in R to help me avoid loading the whole file.
