[R] what is f_eval? It has broken the HH package

I am preparing for the new semester and have downloaded and installed R-3.3.2 for Macintosh and Windows, and then the HH package and its dependencies for both. Everything fresh off CRAN. All works correctly on the Macintosh. On the Windows 10 I am getting an error > library(HH) Loading required p

That is right, Bob. Only one loop for now, since I do not know how to set up the 2nd loop. Any advice from the community? Thank you! Sent from my iPhone > On Jan 12, 2017, at 4:49 PM, Robert Sherry wrote: > > I only see one for loop in your code. I am wondering if you want a second for > l

Re: [R] for loop in R

I only see one for loop in your code. I am wondering if you want a second for loop based upon the length of newdata. I would also think that you do not need the second call to set.seed. Bob On 1/12/2017 4:44 PM, Jennifer Sheng wrote: Dear friends, I am working on a double loop using for. On

Re: [R] Qvalue package: I am getting back 1, 000 q values when I only want 1 q value.

Hi Tom, >From a quick scan of the docs, I think you are looking for qobj$pi0. The vector qobj$qvalue seems to be the local false discovery rate for each of your randomizations. Note that the manual implies that the p values are those of multiple comparisons within a data set, not randomizations of

Aye, but this: some_dates <- as.POSIXct(c("2015-12-24", "2015-12-31", "2016-01-01", "2016-01-08")) (year_week <- format(some_dates, "%Y-%U")) ## [1] "2015-51" "2015-52" "2016-00" "2016-01" (year_week_day <- sprintf("%s-1", year_week)) ## [1] "2015-51-1" "2015-52-1" "2016-00-1" "2016-01

[R] Qvalue package: I am getting back 1, 000 q values when I only want 1 q value.

Hi all, I'm wondering if someone could put me on the right path to using the "qvalue" package correctly. I have an original p value from an analysis, and I've done 1,000 randomisations of the data set. So I now have an original P value and 1,000 random p values. I want to work out the false discov
