Remove all your as.integer() and as.double() coercions. They are unnecessary (unless you are preparing input for C code; also, all R non-integers are double precision) and may be the source of your problems.
Bert, When I remove coercions the script produces warnings like this: 1: In mean.default(fps, na.rm = TRUE) : argument is not numeric or logical: returning NA and str(vel) displays this: 'data.frame': 565675 obs. of 6 variables: $ year : chr "2016" "2016" "2016" "2016" ... $ month: int 3 3 3 3 3 3 3 3 3 3 ... $ day : int 3 3 3 3 3 3 3 3 3 3 ... $ hour : chr "12" "12" "12" "12" ... $ min : int 0 10 20 30 40 50 0 10 20 30 ... $ fps : chr "1.74" "1.75" "1.76" "1.81" ... so month, day, and min are recognized as integers but year, hour, and fps are seen as characters. I don't understand why.
