Cut function in R -


my dataset class has "time" feature. feature belongs character class. try show frequency of pick per different time slot.for reason, used "cut" function below:

freqpickuptime <- cut(dt$time, breaks = "hour")

but, occur below error.

error in cut.default(dt$time, breaks = "hour") :'x' must numeric.

is there solution use cut function character features.

as mrflick says, cut() won't cut characters.

say df$time looks like: 16:42, 12:32, 03:20...

for example:

time <- paste0(round(runif(1000, 0, 23), digits = 0), ':', round(runif(1000, 1, 59), digits = 0))

you do:

table(substr(time, 1, regexpr(':', time)-1))
