Forgive me in advance for trying to use my excel logic in R, but I can't seem to figure this out. In a function, given X I am trying to find out if the row prior to it has a greater value or not using simple logic. If it is, show in the new column as "yes" if not "no".
Here is the sample data:
temp <- data
GetFUNC<- function(x){
temp <- cbind(temp, NewCol = ifelse(temp[2:nrow(temp),8] > temp[1:(nrow(temp)-1),8], "yes","no"))
}
lapply <- GetFUNC(test)
Just so you can see column 8 it looks like this:
testdata$volume
[1] 32216510 10755328 8083097 6878500 8377025 6469979 10675856 8189887 5337239
[10] 5156737
The error:
Error in data.frame(..., check.names = FALSE) :
arguments imply differing number of rows: 11, 10
Thanks for any insight you can provide!
David
