Adding rows to dataframe is easy with rbind but i find that smartbind is often better at handling exceptions such as dataframes with different columnnames and so on.
However Iteratively adding rows in smartbind produces an additional row in some instances:
library(gtools)
alldf <- data.frame()
for (i in 1:3) {
df <- data.frame(x=i)
alldf<- smartbind(df,alldf)
}
smartbind :
> alldf
x
1 3
2:1 2
2:2 1
2:3 1
rbind :
> alldf
x
1 3
2 2
3 1
I don't have a clue why smartbind does this, i've tried fiddling with removal of rownames rownames(alldf) <- NULL, but it doesn't seem to change this. I can use rbind instead for now, or i could inititalize the alldf on the first loop, but it seems like a hassle. Plus, I sometimes prefer to use smartbind so i would like to correct this.
Thanks for Reading
