Hello,
You do not assign the pipe output, so put the print statement as the
last instruction of the pipe. The following works.
# file: rhelp.R
library(dplyr)
mtcars %>%
select(mpg, cyl, disp, hp, am) %>%
mutate(
sampdt = c("automatic", "manual")[am + 1L]
) %>%
print()
Then, I've just tested it,
source("rhelp.R")
Hope this helps,
Rui Barradas

Ivan,
I've read ?source and still do not understand where to put either
auto-print
or an explicit print statement. For example,
cor_disc %>%
select(site_nbr,year, mon, day, hr, min, tz, cfs) %>%
mutate(
sampdt = make_datetime(year, mon, day, hr, min)
)
print(cor_disc)
throws an error. I also get an error when the print statement follows the
sampdt assignment.
I need to understand how to get a sourced file that's modified (as these
tibbles are by combining data and time columns into a datatime colune) and
saving the tibble with the new appended column.
