Re: [R] Wolfram Engine for Developers

I think the Wolfram license is for non-profit, i.e. users and NGOs. Companies making a profit should buy a license. IMHO, the strategy is to increase Wolfram user base. For R and RStudio, it would make sense to add Wolfram to become a comprehensive solution to do science. R is of course mostly sta

Re: [R] Wolfram Engine for Developers

Even from a cursory glance, it is clear that this product is not Free Software, not even Free as in Beer. It cannot be used by end users of open source projects unless you apply for a special license from Wolfram, which I strongly suspect would render the whole project in violation of the GPL li

Re: [R] How to create Pivot table in r?

Hi Rui and Richard, Thank you very much for the help. You are very smart and your code saved my time tremendously. I added one line and got the results what I was looking for it. After "agg", I added dcast function agg <- aggregate(as.character(ID) ~ site2 + site1, daT1, paste, sep = ", ") name

[R] [R-pkgs] Update for R package KScorrect for K-S goodness-of-fit tests

Greetings, We wanted to announce v. 1.4.0 of the R package 'KScorrect', which carries out the Lilliefors correction to the Kolmogorov-Smirnoff (K-S) test for use in (one-sample) goodness-of-fit tests. Aside from several minor changes, the biggest change is that the Monte Carlo algorithm now

[R] Wolfram Engine for Developers

Wolfram Engine for Developers is now free (under some circumstances). Is it possible to call Wolfram from R, especially from RStudio? Being able to do this would significantly increase the potential of R, I believe. [[alternative HTML version deleted]] ___

Hello, Would the following do it? agg <- aggregate(as.character(ID) ~ site2 + site1, daT1, paste, sep = ", ") names(agg)[3] <- "ID" agg #   site2  site1    ID #1 2015-03-09 2015-03-03  A451 #2 2015-04-17 2015-03-03  A253 #3 2015-03-09 2015-03-30  CBA8 #4 20

[R] How to set scale of color scatterplot points relative to a third variable?

Hello Kind and Generous Volunteers, I'm trying to use a scatter plot to visualize three variables: time, radius, and intensity. I would like each point on the scatterplot to be colored according to a gradient, in which red indicates an intensity less than 1, white indicates an intensity of 1, a

Re: [R] How to create Pivot table in r?

Hi Rui, Thank you very much for the code. It is great as it gave the number of individuals encountered in each cell but- is it possible to see which individuals were in that cell? for example - site2 (2015-05-02) and site2(2015-03-31) has value 2, is it possible to show these two "941FD","8737SP"

Re: [R] Help on MFAmix to Reduce Dimensions for a Genetic Dataset

Please read the Posting Guide (again?). 1) Most attachments are stripped by the mailing list. Yours was. It is far more practical to embed a small subset of data in the email as the output of dput() than to attach files. 2) This is the R-help mailing list, but your question has no R code in it.

Re: [R] How to create Pivot table in r?

Hello, Maybe you want to take a look at function xtabs. xtabs(~ site2 + site1, daT1) Note that the results are different if you convert to class "Date" first. daT1$site1 <- as.Date(daT1$site1, format = "%d-%b-%Y") daT1$site2 <- as.Date(daT1$site2, format = "%d-%b-%Y") xtabs(~ site2 + site1, da

[R] Help on MFAmix to Reduce Dimensions for a Genetic Dataset

Dear R Help Members, I am a student from Washington University in St. Louis and I am working on a genetic project in R. In this dataset, there are 497 rows and 11,226 columns. Every row is a genetic marker series for a particular hybrid, and every column is a genetic marker with value 1, 0, -1

Hi R users, I was trying to create a pivot table (cross tabulated) by Site1date (rows) and Site2 date (columns), and spent substantial time but no luck to create it. Is there any possibility to create it? I would be very grateful to your help. "daT1" is row data, in which three columns (speciesID
