Hi
Why you are so reluctant to use dput for sending us part of your data?
The result of str indicates that that SCH_TIME is character vector in which
some values are time and others are **empty** strings. But empty string does
not mean it is missing string.
***Empty bottle of whisky is not missing bottle of whisky***.
So is.na correctly finds that none of your values are missing.
see this example
test<-sample(letters[1:5], 10, replace=T)
test[5:7]<-NA
str(test)
chr [1:10] "b" "a" "d" "e" NA NA NA "d" "d" "c"
table(is.na(test))
FALSE TRUE
7 3
test[5:7]<-""
str(test)
chr [1:10] "b" "a" "d" "e" "" "" "" "d" "d" "c"
table(is.na(test))
FALSE
10
Cheers
Petr
