Hi, Paul.
Not sure if you want to drop only cases out of limits or entire rows
with any case out of limits.
When I face similar tasks to select only cases, I write a function to
select the cases, like:
subset.zscore <- function(x){
? ifelse(x > -3 & x < 3, x, NA)
}
and use it to identify the cases. So if I have this dummy object:
a <- seq(from=-5, to=5, by=.01)
b <- seq(from=-6, to=4, by=.01)
df.original <- data.table::data.table(sample(a,100,replace = TRUE),
????????????????????????????????????? sample(b,100,replace = TRUE))
I would now subset? the cases (not entire rows):
df2 <- df.original[,lapply(.SD,(subset.zscore)]
Note that I use data.table package. You would need to convert your
data.frame object into data.table before to run this code.
I hope this helps you.
Best,
Pedro Paulo.
