Hello all, I am manipulating a large database with 70,000 records. "strptime" generates a date variable but R treats some of the values as NA. I attach a simple example below. I have spent hours on this problem. Any hint would be greatly appreciated. Many thanks, Edwin Sun # =======start of sample code ============= > x <- c("2005-04-02 19:03:00", "2005-04-03

Hello dear R help members. I am trying to understand the anova.rq, and I am finding something which I can not explain (is it a bug?!): The example is for when we have 3 nested models. I run the anova once on the two models, and again on the three models. I expect that the p.value for the comparison of model 1 and model 2 would remain the same, whether or not I add a third model to be compared

On a Unix machine I ran caret::rfe using the multicore package, and I saved the resulting object using save(lm2, file = "lm2.RData"). [Reproducible example below.] When I try to load("lm2.RData") on my Windows laptop, I get Error in loadNamespace(name) : there is no package called 'multicore' I completely understand the error and I would like to ignore it and

Dear R community I have tried to run the diagnostics on my lm object with the gvlma package but it gave me an error with the following message: Non compatible arguments I post here my syntax and session info: RegreC3<-lm(Classification_Score~C3L+Age_+Dx,data=DB1)summary(RegreC3) library(gvlma)gvmodel <- gvlma(RegreC3) R version 2.13.1 (2011-07-08)Platform: i386-pc-mingw32/i386 (32-bit)

Dear users, By running the script below, R crashes systematically at the last command, namely dev.off(), on Windows 7, but not on Windows XP. I therefore don't provide a reproducible example and do not really extract the relevant parts of the script because it has most likely nothing to do with the script itself. I can do it though if you think it might be relevant. R crashes on Windows

Dear useRs, I am using the gamm function in the mgcv package to model a smooth relationship between a covariate and my dependent variable, while allowing for quantification of the subjectwise variability in the smooths. What I would like to do is to make subjectwise predictions for plotting purposes which account for the random smooth components of the fit. An example. (sessionInfo() is at

Hello all I'm trying to learn how to fit a nested model in R. I found a toy example on internet where a dataset that have?3 areas and 4 sites within these areas. When I use Minitab to fit a nested model to this data, this is the ANOVA table that I got: Nested ANOVA: y versus areas, sites Analysis of Variance for y Source DF SS MS F P areas 2 4.5000 2.2500

This problem is likely to be specific to Windows, and particularly Win7. After a successful build of a package (R CMD build addendum), I immediately run an R CMD check for the same package. Not always, but _very_ often, I get the following error: C:\Users\nisabbe\Documents\@Doctoraat\R>R CMD check addendum Loading required package: tcltk Loading Tcl/Tk interface ... done Loading

Dear mailing list, I have a C function that gives me a wrong result when I run it under Windows 7.

Hello, I would like to fit correlation structures with nlme, but R crashes. My data is similar to the "growth of orange trees" example from Pinheiro and Bates (2000), but data are not equally spaced in time, as the last observation is taken after 6 days ( and not 2 as the others). This is the code I'm using: library(nlme)

Some help with how to re-label the vertical axis in a histogram would be appreciated. qplot(off.sc,weight=rel.freq,binwidth=.29,main="test Figure"+ylab("New from inside"))+ylab("New from outside")+ xlab("off.sc\nAggregated frequency plots for 17 equal intervals.") The code

Hi there, Being a relatively happy Rails user I suddenly noticed that string#capitalize and friends do not play well with international characters well. Sample console session: $ ./script/console Loading development environment (Rails 2.2.3) >> $KCODE => "UTF8" >> "яблоко".capitalize => "яблоко" Where "Яблоко" was expected (Russian word

This question seemed to me to be more appropriate for r-devel than for r-help. My apologies if this is not the case. Recently I installed ``cairo'' on my lap-top so that I could make use of the (newish) polypath() function, with on-screen graphics. (The polypath() function does not work with X11(type="Xlib").) The installation went smoothly, X11(type="cairo") works

Hello everyone, I'm trying to parallelize an R script I have written. To do this, I am first trying to use the multicore package, because I've had some previous success with that. The function I'm trying to parallelize is illumqc. I'd like to create a separate process for each of 8 files, contained in the vector "files". Below is my code: for(i in

Hi Everybody I want to print a latex table containing math characters in the column heading These are the formulae I want to use as column headings. It prints OK from TeX $\sum_{i}\sum_{j}C_{P,i,j,y}\times\mathit{FC}_{i}$, $XU_{alt,y}$, $n$, $\bar{C}_{P,y}$ My plan was to create a character vector with these and later rbind the values to them. When I create the vector like:

How do you capitalize each word in a string? Essentially, Ruby''s version of PHP''s ucwords()? Thanks. -- Posted via http://www.ruby-forum.com/.

I'm fairly new to the silhouette functionality in the cluster package, so apologize if I'm asking something naive. If I run the 'agnes(ruspini)' example from the silhouette section of the cluster package vignette, and assign colours to clusters, two clusters have what appear to be incorrect colours in the silhouette plot. library(cluster) data(ruspini) ar<- agnes(ruspini)

Are there any workarounds when using capitalize on words with foreign characters (besides, of course, having a string of replaces for each case)? I''m getting results like this: C?TENOIR -> C?Tenoir Joe -- Posted via http://www.ruby-forum.com/.
