[TriLUG] R code problem

[Brian Henning via TriLUG]

Questionably-helpful peanut-gallery suggestion:

I note you have two things referred to as something.out.  Presumably one of those is actually an input.  Consider, if the language permits (I know nothing about R), labeling inputs as inputs (.in, perhaps?) to improve code readability.

Cheers,

Subject: [TriLUG] R code problem

In case there are some R users among the readership:

After reading in .csv file [It has the class: dataframe] and subsetting the columns down to 16 from 71, I want to write a backup .csv with the following code.

At one time something close to the code below worked, but now it does not. Any ideas?

CODE SNIPPET:
pth.out =
"d:/dox/projects/politics/voter_stats/ncvoter_Statewide/vtr-data-results/"
setwd(pth.out)
#getwd() # testing the path
fyl.out = "vtr_all_01.csv" # 7.6 e6 records/rows, 71 variables/columns # all of the above did work.

# now:
write.csv(fyl.out, fyl.out)                  # sep == , # fails: writes two cells or 30 bytes, not the entire dataframe.
And I do not know why

Any thoughts?

Mike R.
