similar to: Patch for src/main/character.c, systematizing recent fix to do_grep

Attached is a suggested patch for src/main/character.c. It does not fix a bug, but rather provides an improvement on the recent extension of do_grep. In essence, instead of four occurences of 'invert ^ LOGICAL(ind)[i]' that accommodate for the option 'invert' added to grep, there is one occurence of 'LOGICAL(ind)[i] ^= invert' that modifies in-place the logical vector of

Hello, I am wondering about the behaviour of strsplit. When the pattern matches the beginning of the search string, the mepty string is added to the result, but that's not the case when the pattern matches the end of the search string: strsplit(" hello dolly ") [1] "" "hello" "dolly" The man for strsplit explains the algorithm: " The algorithm

given what ?identical says, i find the following odd: x = 1:10 y = 1:10 all.equal(x,y) [1] TRUE identical(x,y) [1] TRUE y[11] = 11 y = y[1:10] all.equal(x,y) [1] TRUE identical(x,y) [1] FALSE y [1] 1 2 3 4 5 6 7 8 9 10 length(y) [1] 10 looks like a bug. platform i686-pc-linux-gnu arch i686 os linux-gnu system

Hello, I think I've found a bug in the C function do_grep located in src/main/grep.c. It seems to affect both the latest revisions of R-2-13-branch and trunk when compiling R without optimizations and with it's own version of pcre located in src/extra, at least on ubuntu 10.04. According to the pcre_exec API (I presume the later versions), the ovecsize argument must be a multiple of 3 ,

Hi all, Based upon an offlist communication this morning, I am somewhat confused (more than I usually am on most Monday mornings...) about the use of grep() with factors as the 'x' argument. The argument guidance in ?grep indicates: x, text a character vector where matches are sought. Coerced to character if possible. and in the Details section: Arguments which should be

Hello, I'm having some trouble figuring out the correct model specification for my data. The system consists of multiple populations of an organism, which have been genetically sampled for several years. The problem is this: A minority of individuals are found in more than one sample, either they have survived into the next sampling at the same location, or have migrated to another another

I had an obscure bug that boiled down to this ``feature'' in R, Read 3921 items > A = list(aa = 1) > A $aa [1] 1 > if (A$a) print("a is there") [1] "a is there" The test appear to check is A$a is TRUE, but what happen is that it auto-complete (silently), and expand to 'A$aa'. The problem was caused by the fact that I had also a element named

Dear R users, I am trying to fit a GLMM using lmer to a dataset where the brood identity (LNRREIR) is nested within mothers identity. The reason for this is that each mother can have several nests within each year and also between years. I am running the following script (actually I have tried all different combinations with LNRREIR and mother): mod <- lmer(sr~z.hatchday +

Dear all, Myself Vijaykumar Muley working as senior research fellow. By training I am a computational biologist with not a strong knowledge of statistics.

Dear everyone, I'm doing some simulations which involves bootstrapping (using functions written in c loaded with R's dyn.load() function) and maximising the likelihood function with R's nlm() function. I used to run my code in S-plus but because I frequently ran out of memory (because of S-plus' silly memory management), I decided to try porting my code to R. In R (on a linux

The explanation is that quote() is a primitive function and that the argument matching rules do not apply to primitives. That section of the R Language definition should say that primitives are excluded; it is documented in ?.Primitive. -thomas On Thu, 2 Apr 2009 waku at idi.ntnu.no wrote: > Full_Name: Wacek Kusnierczyk > Version: 2.10.0 r48269 > OS: Ubuntu 8.04 Linux 32 bit

SVG starts to become more useful in browsers like Firefox, OmniWeb, Opera and soon Safari. There is a couple problem. Since no browser support svg embedded with img one need to fall back to html from: <object data="/path/to/img.svg" type="image/svg+xml" width="512" height="384">Alt text</object> Second, one need to write the width

Dear all, I have a question on handling of missing values in lmList. My data set have continuous predictor and response, x and y, and a grouping variable group.id. All these variables have NAs and the data set also has several other variables that also contains NAs. To create the lmList-object seems to work fine: y.list <- lmList(y ~ x | group.id, data=mydata, na.action=na.omit) However,

Hi,Has anybody worked with thornthwaite method to calculate the daily evapotranspiration ? I have used the following code to calculate monthly evaporation but what I need is daily evapotranspiration. Epot <- thornthwaite(Tave, lat, na.rm = FALSE) # Evaluates evapotranspiration for each month. Do you have any code which works for daily timestep ? Its more technical question, may be some
