Hi! How to find out which plot function is used when i call plot(hist.default(1:10,plot=F)) and all works fine ? The reason why I would like to know it is that after loading some self written R functions > plot(hist.default(1:10,plot=F)) Error in xy.coords(x, y, xlabel, ylabel, log) : x and y lengths differ > traceback() 5: stop("x and y lengths differ") 4: xy.coords(x, y,

Hi! >library(cluster) In this lib a function called silhoutte.default is defined than on the R prompt it type >silhouette.default Error: Object "silhouette.default" not found R1.9.0 The same error are at R1.8.1 And I knew that a function silhoutte.default are present. But the same piece of code works in R1.6.2 ??? Eryk Dipl. bio-chem. Eryk Witold Wolski @

Hi everybody, I have a data set with a value and a status (positive or negative case) and I want make a ROC Analysis. So, with ROCR Package, I have got the ROC curve (True Positive Fraction [tpf] according 1-True Negative Fraction [1-tnf]). http://r.789695.n4.nabble.com/file/n4469203/01.png But, now I want a new graphic which show the sum of true positive fraction and true negative fraction

I'm using Rprofile file on R1.9.0 startup and inside I'm loading a personal Library which uses winMenuAdd() and I've got this error : Error in eval(expr, envir, enclos) : couldn't find function "winMenuAdd" I hadn't this problem with others R versions. What Can I do now to avoid that? I'm using R1.9.0 under Win98. [[alternative HTML version deleted]]

This is R1.9.0, windows XP I run across the following: It is admittedly silly, but it shouldn't segfault: test <- list(y=1:100, x=rep(NaN, 100)) approx(test, xout=rep(NaN, 10)) Bombs! Kjetil Halvorsen

Hi there, I am using the windows version R1.9.0. I used to be a Splus user. When I used Splus to try some computation, I like to put all my codes in a script file and check them line by line. This way I can keep track of all my thinking and it's very easy to make correction at some earlier steps. Now I can not find this script-file style in R. The software itself doesn't seem to have

Hello, I have R1.9.0 under Windows XP. My program plots several plots using x11() par(cex = 0.75) ...... x11() par(cex = 0.75) ...... x11() par(cex = 0.75) ...... x11() par(cex = 0.75) ...... Sometimes, one of them generates a small frame only with title area "R graphics: Device X (ACTIVE)". The message in the console window is Error in plot.new() : Figure margins too large

I'm seeking some advice on effectively using the new Matrix library in R1.9.0 for operations with large dense matrices. I'm working on integral operator models (implemented numerically via matrix operations) and except for the way entries are generated, the examples below really are representative of my problem sizes. My main concern is speed of large dense matrix multiplication. In R

I'm not sure what is going on with this one -- maybe it will make sense to someone. R1.9.0 under Windows 2000. 1) Start up R. 2) search() # works as expected 3) library(fBasics) # from Rmetrics # but at least one of its required packages is not present on the machine 4) search() # nothing appears at all but the prompt Once all of the required packages are present, then step 3 no longer

Hi folks, I have a question about how to load a dll. First, I use the command > dyn.load("lassofu.dll"); then, I got the message below “NULL Warning message: DLL attempted to change FPU control word from 9001f to 90003”; After I tried to use this dll in one of s functions, I got the message below “Error in .Fortran("lasso", as.double(x), as.double(y), as.double(b),

Hi, I found the same question in the mailing list already a few months ago - but there was no answer to it - so I'll try it again Could somebody help me to solve this following problem?

Dear R-devel This one seems a bit arcane for R-help. I very often use R to call routines written in Delphi (son of Pascal), doing "persistent" memory allocation within Delphi. That is, I start R and load the Delphi DLL; then I use .C to call a Delphi routine which allocates a piece of memory X and returns to R a pointer to X; then I do some more stuff in R; then I call another Delphi

I am wondering why my function works fine in R1.7.1 and R1.8.1 but not in R1.9.0.

The name conflicts in Epi and ROC packages (2 'ROC' functions are the problem) cause the following code to work once, but not twice: library(MASS); data(cats); x = cats[,2] y = ifelse(cats[,1]=='F',0,1) library(Epi); ROC(x,y,grid=0)$AUC library(ROC); AUC(rocdemo.sca(y, x, dxrule.sca)) What is the standard way of resolving name conflicts? Ask maintainers to resolve

I have been doing data analysis/modeling in R, connecting to SQL databases with RODBC (winXP client with R1.9.0 and win2k SQL server 2000). I am now trying to leverage some of the OLAP features to keep the data intensive tasks on the DB server side and only keep the analytical tasks within R (optimize use of memory). Is there any package that would allow to connect to OLAP cubes (as a client

Dear all, Some functions like 'ROC(Epi)' can be used to perform ROC analyssi, but it needs us to specify the fitting model in the argument. Now i have got the predicted p-values (0,1) for the 0/1 response variable using some other approach, see the following example dataset: id mark predict.pvalue 1 1 0.927 2 0 0.928 3 1 0.928 ..................

I intend to port an R project from Linux to Windows. It involves C code that is loaded via dyn.load(). I could manage to produce a 'dll' File using cygwin which seems to be o.k. Now, using dyn.load("pcr.dll") i get: Error in dyn.load(x, as.logical(local), as.logical(now)) : unable to load shared library "c:/cygwin/home/pingu/rt-pcr/pcr.dll": LoadLibrary

Hi, If columns of a data.frame have a names attribute and we rbind two similar data.frames together, the names of the column of the resulting data.frame only has the correct values for the first component and has "" in all other positions. Is this a documented "feature" or a bug? If it is intentional, why? Here is a small example to show what I mean. The same behaviour
