Why does the lubridate::ymd_hms function add an NA observation when the “silent” argument is set TRUE?
Could any one explain why the "silent=T" argument triggers a warning and an NA observation, and tell me how to avoid this?
x <- c("2010-04-14-04-35-59", "20100401120000")
ymd_hms(x, silent=T)
[1] "2010-04-14 04:35:59 UTC" "2010-04-01 12:00:00 UTC" NA
Warning message:
1 failed to parse.

Here, lubridate tries to evaluate "silent=T" as a date format, the argument for removing message being quiet.
lubridate::ymd_hms(x, quiet=TRUE)
[1] "2010-04-14 04:35:59 UTC" "2010-04-01 12:00:00 UTC"
This is because you can pass vector inside a lubridate function :
x <- c("2010-04-14-04-35-59", "20100401120000")
y <- c("2010-04-14-04-35-59", "20100401120000")
z <- c("2010-04-14-04-35-59", "20100401120000")
lubridate::ymd_hms(x, y, z)
[1] "2010-04-14 04:35:59 UTC" "2010-04-01 12:00:00 UTC"
[3] "2010-04-14 04:35:59 UTC" "2010-04-01 12:00:00 UTC"
[5] "2010-04-14 04:35:59 UTC" "2010-04-01 12:00:00 UTC"
So here, with silent=T, you're telling lubridate that silent=T is a vector to parse. Hence the NA.
