convert string to date

[hklovs]

Hi,
I need help converting a variable of string to date. I have tried converting the column with (as.Date) but since the format of data is unconventional all I get is NA as value.

glimpse (data1$proxy)
Factor w/ 97 levels "01dec2011","01jun2010",..: 82 65 69 71 90 86 72 56 39 26 ...

Anyone eager to help?

Hi,

You need to select a format that recognize abbreviated month names, in the correct locale. See ?strptime
Packages like lubridate or anytime may help

lubridate::dmy(factor("01Dec2011"))
#> [1] "2011-12-01"
anytime::anydate(factor("01Dec2011"))
#> [1] "2011-12-01"

Also, for date, try to import them as character directly and not factor when you are creating or reading. (see stringsAsFactors in data.frame for example)
