Lightgbm: R package not building because of DCF error (DESCRIPTION file not formatted properly?)

[vinhdizzo]

Hi,

I just downloaded LightGBM this morning and tried to build the R package. I am getting the following error. Seems like the DESCRIPTION file is not formatted correctly.

[vinhdizzo]

I was able to build the R package if I modified the "Description" section of DESCRIPTION to be:

Description: Tree based algorithms can be improved by introducing boosting frameworks.

I think that line might've been too long originally.

Thanks for bringing this to my attention! Will submit a fix soon

@vinhdizzo I was able to reproduce this error on my machine today.

The issue is not the that first line is too long...it's the empty line I added when I added additional information to the DESCRIPTION in #1260 . I think that R does not like any blank lines in the DESCRIPTION file. I will update shortly
