Hi, I recently ran into a problem with 'merge' that stems from the way how missing values in the key column (i.e., the column specified in the "by" argument) are handled. I wonder whether the current behavior is fully consistent. Please have a look at this example: > x <- data.frame( key = c(1:3,3,NA,NA), val = 10+1:6 ) > y <- data.frame( key = c(NA,2:5,3,NA),

Hi, I would like to report a small bug in one of the code examples given in the 'Writing R extensions' manual. Section 5.9.2 ("Calling .External") defines the function "showArgs" in order to demonstrate how to access in C the pair-listed arguments passed by .External. The function aims at printing echoing all passed arguments to the screen but only prints every

Hi While installing RPy2, I had curious problems which, if I traced them back correctly, have their root in the way that libR.so find the R installation directory. I wonder if this might be a subtle bug that only causes problems when one has several versions of R on one system but then can be very annoying and cause very strange behaviour. It seems to me that libR.so asks the Unix shell to

Hello all and thanks in advance for any advice. I am very new to R and have searched my question but have not come up with anything quite like what I would like to do. My problem is: I have a data set for individuals (rows) and values for behaviours (columns). I would like to know the proportion of shared behaviours for all possible pairs of individuals. The sum of shared behaviours divided by

Hi everyone It looks like repeated runs of fastICA produce quite significantly different mixing matrices (not only in terms of sign and row order). I'm not a specialist, so would appreciate any advice on whether this should really be the case: > res3 = > fastICA(af[,2:20],4,alg.typ="parallel",fun="logcosh",alpha=1,method="C",row.norm=TRUE) colstandard >

Dear John Fox and everyone, I have been using the effects library with glms and have found it very useful. Now I'm trying it with lms and I'm not sure if the results of the allEffects() are as expected. I've got a model that looks like this: mymodel = lm(formula = A ~ B + C + D + B:D + C:D) Residuals: Min 1Q Median 3Q Max -3.80156 -0.73486 -0.09792

But it is not taken 'verbatim from src/main/print.c' (at least not in that version of R), and the code is not run with USE_RINTERNALS defined when write-barrier checking is enabled. The example has been updated to match the current code in 2.7.0 alpha. On Sun, 30 Mar 2008, sanders at fs.tum.de wrote: > Full_Name: Simon Anders > Version: 2.6.2 > OS: Ubuntu Linux >

Hi The cor function in the stats package calculates the correlation between columns of data, does anyone know if it is at all possible to calculate the correlation between rows instead ? Or is there an appropriate package or function that is more appropriate I'd like to calculate spearman & pearson correlations between rows. Many thanks Jason -- --------------------------------

Folks   I've managed (due to me being fat-fingered that morning) to get a DNS zone in a Samba-4 DNS setup screwed up.   Basically I was trying to add a new A record to an internal domain "e2eservices.co.uk" using the MS administration tools (not the samba-tool CLI). However instead of adding the entry "styx" to the domain, I accidently added

Greetings all!

Hello Everyone, We have a replicated Gluster volume with three nodes, and we face a strange issue whenever we need to restart one of the nodes in this cluster. As per my understanding, if we shut down one node, the Gluster mount should smoothly connect to another remaining Gluster server and shouldn't create any issues. In our setup, when we stop Gluster on any of the nodes, we mostly get

Hello, I have come across some unexpected behaviour of the function heatmap in the stats package. This looks like a bug to me, but I might have misunderstood something. When calling the function in symmetric mode, the ColSideColors are plotted correctly, but RowSideColors appear in reverse order. This code (modified from the example on the help page) demonstrates the problem: cU <-

Dear R users, As substitute() help page points out: Substituting and quoting often causes confusion when the argument is 'expression(...)'. The result is a call to the 'expression' constructor function and needs to be evaluated with 'eval' to give the actual expression object. And indeed I am confused. Consider: > dat <- data.frame(x=1:10,

Dear R developers, I've just encountered one "feature" of R-C extensions. If it is known, I would be thankful for any hints why it works this way (I found the way around, which is also mentioned here, but maybe it is not the best one). If it is however unknown, it might be considered for a "wish list". Consider a simple "aka" C function (the original

Hi Community, I have a question about how to pass command line parameters to R script running in the batch mode. The problem is: there is a banch of data files which are to be processed by R script called from a web-server, i.e. in the batch mode. The web server generates data files and passes their names calling 'R CMD BATCH' one by one for every file. Now the question is how to

Hi, normally, when we shut down or reboot one of the (server) nodes, we call the "stop-all-gluster-processes.sh" script. But i think you did that, right? Best regards, Hubert Am Mo., 5.

Hi, I would like some extra information on the 'cgh' package in R. I noticed that there isn't much activity regarding this package on the R and BioC mailing list (I googled it). I started using this package and I have few questions: 1/ As I have a custom tiling like array @8um features resolution (affy), I have a lot of probes to work with. I'm assuming it is correct to
