Hi everyone, I have bunch of date and time observations in the format %Y-%m-%d %I %M %S %p. I used strptime() to read this format. But the problem is some of the times are in the format of %I %M %p, so for those times, strptime is giving me NA values.
For example, strptime(paste("2009-04-08","1:49:47 PM"),format="%Y-%m-%d %I:%M:%S %p") [1] "2009-04-08 13:49:47" But strptime(paste("2009-04-08","1:49 PM"),format="%Y-%m-%d %I:%M:%S %p") [1] NA Now I have approximately 10000 observations, so I can't go through all the observations individually in order to find which row in the array has this format. Can anyone suggest me how to handle this issue? Is there any way to convert %I %M %p format to %I %M %S %p? Thanks in advance for the help.
