Several authors hav addressed this problem with names that resemble
"rbindfill". In my machine I find four instances:
??rbindfill
Help pages:
ffbase::ffdfrbind.fill rbind for ffdf where missing columns are
added if not available in one of the ffdf objects
plyr::rbind.fill Combine data.frames by row, filling in missing
columns.
plyr::rbind.fill.matrix Bind matrices by row, and fill missing
columns with NA.
rockchalk::rbindFill Stack together data frames

Hi Bhaskar,
If you are using read.table or similar, see the "fill=" argument.

Hello Everyone,
I am trying to extract data from a url. The codes work well when the
data structure is as follows:
X Y
1 2
1 5
1 6
1 7
3 4
However, the code fails when the data structure has no number
under the 2nd column (shown below).I get the following error:
"Error in data.frame(..., check.names = FALSE) :
arguments imply differing number of rows: 242, 241"
X Y
1 2
1
1
1 7
3 4
Can anyone please help me in how I can modify the codes ( shown below) to
adjust for the above mentioned condition
in the data structure.
library(rjson)
url <- "abcd.com"
json_data <- fromJSON(file= url)
d3 <- lapply(json_data[[2]], function(x) c(x["data"]))
d3 <- do.call(rbind, d3)
X_Dataframe = as.data.frame(unlist(d3[[1]]))
b <- do.call("cbind", split(X_Dataframe, rep(c(1, 2), length.out =
nrow(X_Dataframe))))
regards,
bhaskar
