Re: [R] Converting "list of data frame" to data frame

This does not look like a "list of dataframes" where each dataframe is an element of the list. This appears to just be a list with all the elements of the data frames at the same levels. A list of data frames would look like this: > x <- list(data.frame(a=1:5, b=1:5), data.frame(a=6:10, b=6:10))

Greetings Douglas/Jim/John/R-help, Thanks for your help so far. Answering your questions - doing an "str' on the list reveals following (head) information : --- $ : Factor w/ 729 levels "XX1","YY1",..: 6 9 10 12 13 14 19 22 29 30 ... $ : int [1:109] 19950201 19

I just tried an artifical example and the approach seems to work okay # Joining data.frames stored in a list # From "Douglas Bates" aa <- 1:4 bb <- 2:5 cc <- 3:6 dd <- 4:7 ee <- 5:8 ff <- c(rep(NA,4)) gg <- 6:9 lst <- list(data.frame(aa,bb), data.frame(cc,dd), data.frame(ee,ff,gg)) tatiana <- n

since you didn't supply a reproducible example, here is a test that I ran with varying number of rows that seems to work fine. You might want to provide at leat an "str" of the structure that you are doing the rbind on. > x <- lapply(1:10, function(z){ + data.frame(a=runif(z), b=rnorm(z), c=

Douglas/R-help, Thanks for your reply. I did try the solution but the result is not what I expect and I also get the following warning message: --- Warning message: number of columns of result is not a multiple of vector length (arg 1) in: rbind(1, c(6, 9, 10, 12,

Greetings, This might be something very simple but a nice solution eludes me!! I have a function that I call within sapply that generates data frame in each call. Now when sapply returns me back the result - it's in the form of a "list of data frames". so in order to extract the infor
