I'm trying something that I thought would be pretty simple, but it's proving quite frustrating... I want to display, for instance, the correlation coefficient "rho" in a graph. I can do something like: text(x, y, paste("rho =", cor)) where cor would be my previously calculated correlation coefficient, and x and y the coordinates. Obviously that displays

Hi, Does anyone know an easy way of retaining rows in a model.matrix where missing values are present in the predictors. Ideally I'd be able to retain these rows as zeros. Thanks, Jarrod -- The University of Edinburgh is a charitable body, registered in Scotland, with registration number SC005336.

Hi, I am having trouble getting \alt (or \altenv) to work with Schunk/Sinput and was wondering if anybody had had success? With the slide \begin{frame}[fragile]\frametitle{Basic R} \alt<2>{ <<echo=TRUE>>= 2+2 @ }{ <<echo=TRUE, eval=FALSE>>= 2+2 @ } \end{frame} I get the error message: !

Hi, I am sorry if this is perceived as a C++ question rather than an R question. After uploading an R library to CRAN (MCMCglmm) the C++ code failed to pass the memory checks. The errors come in pairs like: Mismatched free() / delete / delete [] at 0x4A077E6: free (vg_replace_malloc.c:446) by 0x144FA28E: MCMCglmm (MCMCglmm.cc:2184) Address 0x129850c0 is 0 bytes inside a block of size 4

Hi, I was wondering whether there was an easy way to change the attributes of all elements in a data.frame (rather than looping through elements)? Specifically, I would like to set the "dim" attributes to NULL Thanks for any help, Jarrod -- The University of Edinburgh is a charitable body, registered in Scotland, with registration number SC005336.

Hi, I'm using valgrind to check over some C/C++ code for an R library. I'm getting the report (see below), but can't track down the uninitialised value(s). I tried using --track-origins=yes in valgrind which gives: ==28258== Uninitialised value was created by a stack allocation ==28258== at 0xEE33D98: ??? (in /usr/lib64/R/lib/libRlapack.so) I presume the problem is an

I'm trying to annotate some graphics using plotmath and finding out that the code I'm using isn't bolding the greek letters - it bolds the rest (once I adjusted the numerics to characters), it's just failing on the greek characters. Any suggestions welcomed. Jim Price. Cardiome Pharma Corp. Test code: plot(1:5, type = 'n') # The not bold version text(2, 2:4, cex =

Hi, I have a dataset with a continuous response variable and, among other predictors, an ordinal variable. Here is what it could look like treatment <- factor(rep(c("AA", "AC", "AD","AE", "AB"), each = 10)) length <- c(75, 67, 70, 75, 65, 71, 67, 67, 76, 68, 57, 58, 60, 59, 62, 60, 60, 57, 59, 61, 58,

Hi, Is the following function built in somewhere? concat = function(v) { res = "" for (i in 1:length(v)) res = paste(res,v[i],sep="") res } e.g. > concat(c("12","3","45")) [1] "12345" Cheers, Andy -- Andy Fugard, Postgraduate Research Student Psychology (Room F3), The University of Edinburgh, 7 George

I would like to use greek "tau" as a symbol of variable to integrate over in plotmath expression(integral(f(tau)*dtau, 0,t)) but nothing seems to work. I tried d{\tau}, d\tau, etc., without any success Is it possible? How can I accomplish this?

Hi there, Am I correct to believe that tetrachoric correlation is a special case of polychoric correlation when there are only two levels to the ordered factor? Thus it should be okay to use hetcor from the polycor package to build a matrix of correlations for binary variables? If this is true, how can one estimate 95% confidence intervals for the correlations? My guess would be mat =

Here's a patch (against 2.2.2) which adds battery.temperature to the ietf-mib snmp driver. While looking at ietfmib.h I noticed that the value for IETF_OID_IN_LINES is actually that for upsOutputNumLines.0.

Hello I'm new to R (one week) so please excuse any obvious mistakes in my code or posting. I am attempting to fit a non linear function defining the relationship between dependent variable A and the variables PAR and T grouped by the condition Di. The following steps are taken in the Rcode below: 1) load the data (not shown) 2) define the function to be fit 3) define the starting values

Does anyone know, or know documentation that describes, how to declare multiple values in R as missing that does not involve coding them as NA? I wish to be able to treate values as missing, while still retaining codes that describe the reason for the value being missing.

Dear all, The background is that I'm trying to fix this bug in the geometry package: https://r-forge.r-project.org/tracker/index.php?func=detail&aid=1993&group_id=1149&atid=4552 Boiled down, the problem is that there exists at least one matrix X for which det(X) != 0 and for which solve(X) fails giving the error "system is computationally singular: reciprocal condition

Dear all, I'm attempting to use a piecewise regression to model the trajectory of reproductive traits with age in a longitudinal data set using a mixed model framework. The aim is to find three slopes and two points- the slope from low performance in early age to a point of high performance in middle age, the slope (may be 0) of the plateau from the start of high performance to the

Dear All, I am working on a dataset having the dependent variable as ordinal data(discrete data) and multiple independent variables. I need to find the likelihood for the NULL model.i.e the model with only the dependent variable and all other independent variables as zero. Kindly let me know how to find the likelihood for a NULL model in R. Is there any specific function in R that can do
