Re: [R] Extract from a text file

Hi Val, Take a kook at read.table. If for some reason the file dosen't have the same separator between the columns you can use strsplit after loading the file. This might helpyou along getting data into R: http://www.statmethods.net/input/importingdata.html Best On Tue, 31 May 2016, 02:15 Val,

Mark, you can follow the bouncing emails by looking at the raw message headers. How you would access them depends on your email client, but "Received:" headers appear in reverse chronological order above the "From:" line, indicating the times when the email had reached various servers in its

[R] graphic device Windows tickmarks

Dear List, I discovered an issue; when plotting (base) in R, the tickmark-labels are slightly off (Windows machine). Thus, when saving the plot in R with x11() and dev(...) the plot-tickmarks shift, see the example below. Session Info: R version 3.2.3 (2015-12-10) Platform:

Hi all, I'm seeing the natural sequencing of email threads getting corrupted. For example, a May 26 thread on subject 'Shaded areas in R' would have been initiated by an email at 6:58am. However I did not get that email until 1:48pm, preceded by 3 replies to the post. Trivial but irritating.

Dear Hanna, None of the models are correct is you want the same random intercept for the different methods but different random slope per method. You can random = ~ 1 + time:method | individual The easiest way to get alpha_0 and tau_i is to apply post-hoc contrasts. That is fairly easy to do
