问题:

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

resave

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.)

回答1:

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") ) )

回答2:

I'll vote for the other answer, but here's some almost working code:

resave

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
