As a total novice and somebody lurking in the background who doesn't have a need to use R regularly except for a one-time project, I also am surprised by (really mainly one or two) people who answer most posts by telling people to do their homework, spend more time studying R, etc. Even novices know these things, and so those replies are totally unhelpful.
For novices who have a "one time" need to use R for a project, we cannot spend months studying as if we were going to use it every day in our jobs. We simply read some tutorials, some books, etc. and when we run into an issue that we cannot resolve, we ask for help. I thought that was what forums such as this were about - people who voluntarily answer questions for free because they are interested in the subject. That said, I agree totally about the need to be clear and concise when posting questions. But as a novice, we sometimes are not sure exactly what the relevant information is that is needed to answer our question. In summary, how about cutting novices some slack? If you don't want to answer a post in a helpful way, then just ignore it. You don't need to interject yourself into every post. -----Original Message----- From: R-help [mailto:r-help-boun...@r-project.org] On Behalf Of Damjan Krstajic Sent: Monday, December 11, 2017 6:37 PM To: Bert Gunter <bgunter.4...@gmail.com>; Jeff Newmiller <jdnew...@dcn.davis.ca.us> Cc: R-help <r-help@r-project.org>; Berry, Charles <ccbe...@ucsd.edu> Subject: Re: [R] Gaussian Process Classification R packages For the record please re-read my original message. It is clear, concise, polite and thankful for future help. I received a reply "Google it!". Thank you! Thank you Jeff for your links. I am aware of them. However, they do not point to an R package for GP for binary classification which produces prediction intervals. It seems that r-help is not as it was before. Wish you all the best. Roger and out. ________________________________ From: Bert Gunter <bgunter.4...@gmail.com> Sent: 12 December 2017 00:01 To: Jeff Newmiller Cc: R-help; Damjan Krstajic; Berry, Charles Subject: Re: [R] Gaussian Process Classification R packages For the record: I **was** trying to be helpful.

The OP's hostile response frankly surprised me, but I see no reason to respond in kind.
