Question
I'm trying to use the R code from this answer to convert a bunch of rdata files to CSV.

Russianresave <- function(file){
e <- new.env(parent = emptyenv())
load(file, envir = e)
objs <- ls(envir = e, all.names = TRUE)
for(obj in objs) {
.x <- get(obj, envir =e)
message(sprintf('Saving %s as %s.csv', obj,obj) )
write.csv(.x, file = paste0(obj, '.csv'))
}
}
resave('yourData.RData')
However on one of the files I'm getting this error:
Error in data.frame(`2` = list(pos = c(6506L, 6601L, 21801L, 21811L, 21902L, :
arguments imply differing number of rows: 7670, 9729, 114, 2422
Calls: resave ... as.data.frame -> as.data.frame.list -> eval -> eval -> data.frame
I tried searching for the error message but I can't really make heads or tails of it.
Was that rdata file created improperly somehow?
Is there a better way I should convert arbitrary Rdata files to CSV? (I Don't know the names of the objects inside the files ahead of time.)
Update:
Here's what I'm seeing in that rdata file. If it's any help?? (Keep in mind I can't really edit the rdata files so I'm trying to figure out something that will convert them to CSV as is.)
> load("indiv8-hmmprob.RData")
> ls()
[1] "dataa"
> write.csv(dataa, file="greg.csv")

Solution
That answer was designed to handle object of class-'data.frame'. You only have an object of class-'list' which happens to have items that are dataframes. So there isn't an object with the name "2" in you workspace but there is an element in the 'dataa'-list that is named "2" and all of the other elements appear to also be dataframes, so why not use:
lapply( names(dataa), function(nam) write.csv( data[[nam]], file=paste0(nam, ".Rdata") ) )
OTHER TIPS
I'll vote for the other answer, but here's some almost working code:
resave <- function(file){
e <- new.env(parent = emptyenv())
load(file, envir = e)
obj <- get('dataa', envir =e)
lapply( names(obj), function(nam) {
write.csv( obj[[nam]], file=paste(nam, ".csv", sep="") )
cat(sprintf('%s.csv
', nam) )
}
)
}
resave("indiv8-hmmprob.RData")
Here's the output. which works but it's throwing in some wierd printed stuff at the end, the [[1]] NULL, etc.
2.csv
3.csv
4.csv
X.csv
[[1]]
NULL
[[2]]
NULL
[[3]]
NULL
[[4]]
NULL
