[R] Difference subsetting (dataset$variable vs. dataset["variable"]

Hi All, I thought dataset$variable is the same as dataset["variable"]. I tried the following: > str(ZWW_Kunden$Branche) chr [1:49673] "231" "151" "151" "231" "231" "111" "231" "111" "231" "231" "151" "111" ... > str(ZWW_Kunden["Branche"]) 'data.frame':49673 obs. of 1 variable: $

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 jo

Hi Mark, As with most other annoying, time-consuming operations in the internet and computing in general, blame the spammers and the scammers. The R help list is attacked by both and requires both automatic and human scanning of messages to minimize intrusions. Unfortunately no one has come up with

[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: x86_64-w64-ming

[R] email threads chronology

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. Th

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 wit
