I'm looking to find a way to trace back the original variable name after a
being passed through a series of functions.
I can get the variables names for the current call easy enough with match.call,
but I'd like to go back further if the function was called from another
function.
Say I have.
I'm sure this has been answered before but alas my googlefoo is not that strong.
I have several .Rdata files with a single object in them. I need to set the
class of the object to "myClass". Unfortunately, I don't know the name of the
object beforehand. Obviously I could ls() and get the name
Thanks a bunch. Can't believe I missed that.

Hello,
The error I get is: Error: object 'res' not found You are using an undefined
variable, 'res'. I don't believe this has something to do with environments.

I have a collection of .RData files that have result objects that I would like
to combine. Specifically, skatCohort objects from the skatMeta package, but
I've run into a similar issue with simple data.frames also.
If I run something like
FILES <- list.files(path="/path/to/my/results", pattern

I have a solution (actually a few) to this problem, but none are
computationally efficient enough to be useful. I'm hoping someone can
enlighten me to a better solution.
I have data frame of chromosome/position pairs (along with other data for the
location). For each pair I need to determine

I'm trying to find a more elegant way of doing this. What I'm trying to
accomplish is to count the frequency of letters (major / minor alleles) in a
string grouped by the factor levels in another column of my data frame.
Ex.
> DF<-data.frame(c("CC", "CC", NA, "CG", "GG", "GC"), c("L", "U", "L

I am trying to remove characters in a string based on the position of a key
character in another string. I have a solution that works but it requires a
for-loop. A vectorized way of doing this has alluded me.
