With the above data, Arizona Diamondbacks baseball, I’m trying to put zeros
into the R1 column is the RunnerFirst column is blank and a one if the column
has a coded entry such as rows 4,5,7,8,& 9. Similarly I want zeros in R2 and
R3 if RunnerSecond and RunnerThird respectively are blank and ones if there is
an entry.
I’ve tried everything I know how to do such as “If Loops”, “If-Then loops”,
“apply”, “sapply”, etc. I wrote function below and it ran without errors but I
have no idea what to do with it to accomplish my goal:
R1 <- function(x) {
if (ari18.test3$RunnerFirst == " "){
ari18.test3$R1 <- 0
return(R1)
}else{
R1 <- ari18.test3$R1 <- 1
return(R1)
}
}
The name of the data frame is ari18.test3
On a more philosophical note, data handling in R seems to be made up of
thousands of details with no over-riding principles. I’ve read two books on R
and a number of tutorial and watched several videos but I don’t seem to be
making any progress. Can anyone suggest videos, or tutorials, or books that
might help? Database stuff has never been my strong point but I’m determined
to learn.
Thanks,
Philip Heinrich
