How do I convert my date and time stamp in R to date only stamp? -


this question has answer here:

i new r. have large data set 1 of columns containing time stamp. format of column content e.g. sat mar 07 18:38:01 est 2015. want create additional column in data frame date. care in second column e.g. mar 07 2015. tried other similar questions addressing different format. in advance !

this works example. let me know if works full data set:

x = "sat mar 07 18:38:01 est 2015"   as.date(x, format="%a %b %d %h:%m:%s est %y")  [1] "2015-03-07"

see ?strptime more information on formatting codes parsing dates , times.

df$date = as.date(df$timestamp, format="%a %b %d %h:%m:%s est %y")
