Dear R fellows,
I created a new column Date_flag to compare the dates of COL1 and COL2 using
the code
below. But it showed that 5/1/15 is greater than 6/1/2014 and 5/1/2015 greater
than
7/1/2014 despite the year is greater. How do I fix that? I did try to format as
%y/%m/%d
but it does not f

Dear R Fellows,
I Have a dataset( data1) with 2 columns of date showing a class of factor. How
to convert them to date? Then compare them, keep the greater date only in a new
column. Using as.Date to change the class to Date but the data becomes NA.
Much Thanks

Use tm package and create a corpus to capture terms from the TDM within the
corpus. Then you can apply as.matrix() to display terms' occurences. Go to CRAN
and read about tm package.

Since the Dictionary () function is no longer available with the tm package.

occurrences of price, crude, oil in

to return for all 102 docs? See my coding belo
