Re: [R] FOR TAKING PERCENTAGES of OTUS in each column (n=2910 COLUMNs)

If your problem really requires genetics jargon to be expressed, then perhaps you should be asking it in a forum where more of the participants are likely to understand it... like the Bioconductor help forum? https://www.bioconductor.org/help/support/ The Posting Guide mentioned in the footer

[R] FOR TAKING PERCENTAGES of OTUS in each column (n=2910 COLUMNs)

Hi, I am analyzing a huge excel table with OTUs. In the table, I have 2910 columns and 365 rows.Each column represents one individual (n=2910). Rows represent microbial species (n=365). I have the total of all OTUs of microbial species under each column. Then I need to get the percentages of each

[R] Cannot create a visible Choropleth Legend - GISTools

I have combined two layers to create a shapefile which I am colouring using the Choropleth function in GISTools. The problem I am having is that despite having no other problems with my code including with the actual mapping of the choropleth itself, nothing I can do, using choro.legend, actually

Re: [R] Matrix

Effectively you want a circulant matrix but filled by column. Example input vector and number of columns x = c(1:8,19:20) nc = 5 For the result you specifically describe, the following generalises for any vector and any arbitrary number of columns 'nc', padding with zeros as necessary.

Re: [R] Matrix

Well, of course, I *did* make a dumb error (again!!). Here's the corrected version: x <- c(1:5,10:12) ## generate vector of indices by outer and %% i <- seq_along(x) nc <- 4 ## number of columns desired Corrected statement indx <- (outer(i, rev(i-1),"+") %% length(x)) [,seq_len(nc)] +1

Re: [R] Matrix

Clever, Don. Here's a more explicit approach that generalizes (if I haven't made any dumb errors): x <- c(1:5,10:12) ## generate vector of indices by outer and %% i <- seq_along(x) nc <- 4 ## number of columns desired ## get subscripting indices via outer() and %% indx <- outer(i,rev(i),"+") %%

[R] Any reason not to use RUnit any longer?

Hello, I see that quite some packages nowadays use testthat and that RUnit doesn't have recent updates. On the other hand Rccp, fTrading and others (still) test with RUnit. My old code uses RUnit and I would prefer to keep it that way unless there is an important reason to switch to testthat. If

How about this: p0 <- 1:4 matrix( c( rep( c(p0, rep(0, 4)) , times=3) , p0) , 7, 4) Of course, it would take some effort to generalize it to different lengths for p0. -Don -- Don MacQueen Lawrence Livermore National Laboratory 7000 East Ave., L-627 Livermore, CA 94550 925-423-1062 On

Probably should take this question to the R-sig-geo mailing list. And you will need to tell people exactly what command(s) you used, and the exact resulting error message. Possibly you will have to ask for help from Rstudio, if it turns out the cause somehow has to do with Rstudio; I have no
