Description

Hi everyone,

currently, show(dataframe) method shows some information about the columns and their datatypes, however R shows the first N number of rows in dataframe. Basically, the same as showDF. Right now I changed so that show calls showDF.

Also, the default number of rows was hard coded in DataFrame.R, I set it as environment variable in sparkR.R. We can change it if you have other better suggestions.

Thanks,
Narine
