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

The attached patch provides a modification to the recent fix/improvement to do_grep already included in the most recent development version. The original fix added new functionality to the grep function by adding a new parameter, 'invert'. In the source code for the underlying do_grep, the value of the parameter is used to invert the logical match-no match flag vector ind. The

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

hello! i am kyrre and i''m a rails newbie. i''m trying to combine altered beast with chuckslist to create some sort of online community here in norway where i can make friends and maybe even hook up with some lovely ladies. but i feel that the chuckslist part ain''t as up-to-date and well-designed as the altered beast part. it''s not restful for instance, and my

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 +

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

4000:6000 gives you 4000, 4001, ..., 6000.

Hi all, I have gone through some basics of R in eclipse environment. What I need to work is more than basic level so I could not find out the solution by myself. could anyone help me ? My case, I have climate data (precipitation) in nc format with single layer for each time interval in a day. That means for January 1, 2013, I have 8 separate files each containing 3 hrs cumulative precipitation

Hi, I have two lists 1) List1- 30,000 rows and 104 columns 2) List2- a list of 14000 selected rownames  from List 1 Now, I want to extract all the 104 columns of List1  matching with the 14000 selected rownames from List2.  Psedocode will be something like this: match rownames(List2) with rownames(List1) extract selected matched 104 coloumns from (List1) strore in-> List3 So the

Hi Experts, I am newbie in R. Could you please share your idea to create a stack with no value or zero value? Nrow=1,Ncol=1, Ncell=1, I aim to work with looping, I want to make a first layer with zero values to add other layers further. Thanks.

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 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
