R help - Jan 2022 - Error in if (fraction <= 1) { : missing value where TRUE/FALSE needed

I get this error:

Error in if (fraction <= 1) { : missing value where TRUE/FALSE needed

I used this:

var <- ifelse(test$operator == 'T14', 1, 0)

operator has several values like T1, T3, T7, T15, T31, T37

For some values like T3, T7 it works fine but for majority of values it
gives error.

When I use: is.na(ts$operator), it shows all false values so no NAs.

Where could be the problem?

The error must be in a place different from your test$operator
comparison. Have you tried traceback() to get the call stack leading to
the error? Or options(error = recover) to land in a debugger session
the moment an uncaught error happens? (Use options(error = NULL) to go
back to the default behaviour.)

Unrelated: var <- test$operator == 'T14' will also give you an
equivalent logical vector with a bit less work.

Hi

Do not post in HTML, please.
Try to show your real data - use str(test), or preferably dput(test). If
test is big, use only fraction of it
The problem must be probably in your data.

x <- sample(1:20, 100, replace=T)
fake <- paste("T", x, sep="")
ifelse(fake=="T14", 1,0) 
  [1] 0 0 0 0 0 0 0 0 0 0 0 0 1 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0
0 0
 [38] 0 0 0 0 0 0 0 0 0 0 0 0 0 0 1 0 0 0 0 1 0 0 0 0 0 0 0 0 0 0 1 0 0 0 0

 [75] 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 1 0
 
head(fake)
[1] "T7"  "T9"  "T3"  "T9" 
"T12" "T9" 
> str(fake)
 chr [1:100] "T7" "T9" "T3" "T9"
"T12" "T9" "T19" "T19" "T12"
"T2" "T17" ...

Your error and your code don't match. Please spend some time to make a small
reproducible example [1][2] when posting a question... you may even figure out
your own answer before you send it out.
