Hello,
How can I convert date-time in which month and day have non zero padding?
For example: "2015119_06" ("2015-01-19 06:00")
Thanks

Hello R-Helpers,
I have a slight problem with the expresion data[data==""] <- NA which works
well for a data.frame. But now i must use the same for a list of
data.frames.
My idea is data[[]][data==""] but it don´t work.
Thanks!!

Hello R helpers,
I would like to automate this code for many files of the same type. But I
don´t know how to make it. In particular, i don´t know how to read many
files each one as an r object with the name of the file. Then a for loop
would be sufficient, right?
Many thanks and a happy new year.
