Hi, Have I missed something, or misunderstood? The r-help posting guide asks users to contact the package maintainer : "If the question relates to a contributed package, e.g., one downloaded from CRAN, try contacting the package maintainer first. [snip] ONLY [only is bold font] send such questions to R-help or R-devel if you get no reply or need further assistance. This applies to both

Hi, I've added R_init_data_table to the "data.table" package (which has a dot in its name). This works well in R 2.15.0, because of this from the Writing R Extensions manual : " Note that there are some implicit restrictions on this mechanism as the basename of the DLL needs to be both a valid file name and valid as part of a C entry point (e.g. it cannot contain ?.?): for

Hello R Community, Subject: Bayes Factor A Bayesian ANOVA of the form: competitionBayesOut <- anovaBF(biomass ~ clipping, data = competition) Returns the following Error message: Error in (function (classes, fdef, mtable) : unable to find an inherited method for function ?compare? for signature ?"BFlinearModel", "missing", "tbl_df"?

Hi, Similar questions have come up before on the list and elsewhere but I haven't found a solution yet. winbuilder's install.out shows data.table's .c files compiled with -O3 on Win32 but -O2 on Win64. The same happens on R-Forge. I gather that some packages don't work with -O3 so the default is -O2. I've tried this in data.table's Makevars (entire contents) : ====

Forwarded to R-Help, because I think it could interest people following this thread. Clearly, RServe and svSocket have different goals and very little overlap.

Hi I followed a railscast episode and got datatables up and running, beautifully along with the nice jquery-ui as in the front page. The main issue I''m having though is that I suck at CoffeeScript/JS ~_~ I''m trying get the datatables to reload every 1 second but I don’t see any request coming into my webserver for refreshes and hence, no refreshes on the web page itself.

Hello all, is there any data table component for rails which can sort/search/pagination etc? I''ve checked out jquery plugin datatables, which can sort/search/pagination, but for large dataset of course need to go server side, need to pass params[:sort]/params[:search]/params[:pagination] to server side, which involves a lot of code, I''ve checked out rubygems.org and found a

Hello R Community, I inadvertently updated packages via R Studio when a package was open. Now when R Studio is opened the message below appears in the console panel. Error in loadNamespace(name) : there is no package called ?yaml? Error in loadNamespace(name) : there is no package called ?yaml? When running R code, so far the only function that has not worked is datatable () in the ?DT?

Hi, Following previous discussion on this list (http://tolstoy.newcastle.edu.au/R/devel/05/12/3439.html) I have created a package as suggested, and uploaded it to CRAN incoming : data.table.tar.gz. ** Your comments and feedback will be very much appreciated. ** >From help(data.table) : This class really does very little. The only reason for its existence is that the white book specifies

Hi, Does anyone have experience using RJDBC library to write to Sybase datatable? The jdbc driver I am using is jConnect 6.0. I can successfully write into a new datatable, but have problem appending rows to existing one. It either complains "Table *** already exists" or simply overwrite the existing one. Here is the example. I am trying to append 'data' to the existing

Hi Sean, Try : key(test.dt) = c("a","b") Btw, the posting guide asks you to contact the maintainer of the package before r-help. Otherwise r-help would fill up with posts about 2000+ packages (I guess is the reason). In this case maintainer("data.table") returns "datatable-help at lists.r-forge.r-project.org" (cc'd) where you will be very welcome.

Dear R Community, Below is a problem with a simple ggplot2 graph. The code returns the error message below. Error: stat_count() must not be used with a y aesthetic. My code is below and the data is attached as a ?text? file. # Graph of the probabilities library(digest) library(DT) datatable(probability) str(probability) probability$Fertilizer <- as.factor(probability$Fertilizer)

Hi, all. The previous post have a typo: problem in ARM assembly: I use LDR to load an external symbol : LDR R7,=DataTable But clang gives error: unexpected token in operand to the '=', Then I change the code to: LDR R7,DataTable The error becomes: unsupported relocation on symbol. How can I get around this in clang? My problem is actually how to load external symbol in

Hi James, If you want to specify the y-values, you need to use stat="identity" as below: ggplot(probability, aes(x=Fertilizer, y=prob)) + geom_bar(stat="identity", aes(fill=Treatment)) best, huzefa On Tue, Apr 12, 2016 at 1:02 PM, James Henson <jfhenson1 at gmail.com> wrote: > Dear R Community, > > Below is a problem with a simple ggplot2 graph.

It looks like there might be some kind of problem with the Plyr-1.4.1 packages pushed to CRAN? The web pages show 1.4.1 as the current version, but trying to fetch the source through the provided link gives a 404: http://lib.stat.cmu.edu/R/CRAN/web/packages/plyr/index.html $ wget http://lib.stat.cmu.edu/R/CRAN/src/contrib/plyr_1.4.1.tar.gz --2011-04-11 13:19:09--
