Hi,
I would like to process each row of data frame having 8 columns of which I am
interested in 4 columns for my analysis.I tried using apply function but I get
syntax error,although I checked for missing syntaxes ,couldn't figure out the
mistake.Can you also suggest me more efficient way to perform same action.
# creating target column from result
kdata$target <- apply(kdata,1,ifelse((kdata$H1 & kdata$H2 & kdata$H3 &
kdata$H8) ==
1,"all-true",(ifelse(kdata$H1== 0 &
kdata$H2 == 0 &
kdata$H3 == 0 &
kdata$H8 == 0) ,
"all-false","other")))
Thanks.
Alily
