Hi all, I swear this used to work: library(gsubfn) strapply("S(AC,P)TVDK(8)EELVQK(8), ".[(].{1,2}[)]|.")[[1]] But somewhere along the update path it stopped ... now giving me this Error in base::gsub(pattern, rs, x, ...) : invalid backreference 2 in regular expression Can't figure it out. What am I doing wrong? Thanks for any hints, Joh

I have had some comments on sqldf regarding its dependence on tcltk such as the second last sentence on this blog post: http://translate.google.com/translate?hl=en&sl=zh-CN&u=http://www.wentrue.net/blog/%3Fp%3D453&prev=http://blogsearch.google.com/blogsearch%3Fhl%3Den%26ie%3DUTF-8%26q%3Dsqldf%26lr%3D%26sa%3DN%26start%3D10 sqldf does not directly use tcltk but it does use strapply in

I have a matching problem that I cant solve. mystring = "xxx{XX}yy{YYY}zzz{Z}" where "x","X","y","Y","z","Z" basiclly can be anything, letters, digits etc. I'm only interested in the content within each "{}". I am close but not really there yet. library(gsubfn) strapply(mystring,"\\{[^\\}]+",, perl=F)

gsubfn is a package with one function, gsubfn, that is like gsub except instead of taking a replacement string it takes a replacement function. For each match, that match is passed to the replacement function along with the backreferences, if any, and replaced with the output of the function. If the first two arguments are omitted the defaults are set to do perl-style (sort of) string

Hello, I just don't get this and would appreciate if someone could write a line or two: I'm trying to build this package and it stops installing after I add the following to the NAMESPACES file: >importFrom(gsubfn,strapply) The error during the package test is: Error in MyPackage::MyFunction : package 'MyPackage' has no name space and is not on the search path Calls:

note: whole function is below- I am sure I am doing something silly. when I use it like USGS(input="precipitation") it is choking on the precip.1 <- subset(DF, precipitation!="NA") b <- ddply(precip.1$precipitation, .(precip.1$gauge_name), cumsum) DF.precip <- precip.1 DF.precip$precipitation <- b$.data part, but runs fine outside of the function: days=7

A version using regular expressions, regexpr() and substr() functions is attached. Finally everything is packed into splitSeq() function (chunk 14 in the attached file) Seq<- "GCCTCGATAGCTCAGTTGGGAGAGCGTACGACTGAAGATCGTAAGGtCACCAGTTCGATCCTGGTTCGGGGCA" Str<-

Look at the bottom of the message for my question #here is a little function that I wrote USGS <- function(input="discharge", days=7){ library(chron) library(gsubfn) #021973269 is the Waynesboro Gauge on the Savannah River Proper (SRS) #02102908 is the Flat Creek Gauge (ftbrfcms) #02133500 is the Drowning Creek (ftbrbmcm) #02341800 is the Upatoi Creek Near Columbus (ftbn) #02342500 is

Dear list, I have the following text to parse (originating from readLines as some lines have unequal size), st = c("START text1 1 text2 2.3", "whatever intermediate text", "START text1 23.4 text2 3.1415") from which I'd like to extract the lines starting with "START", and group the subsequent fields in a data.frame in this format: text1 text2

Dear list, I'm seeking advice to extract some numeric values from a log file created by an external program. Consider the following example, input <- readLines(textConnection( "some text <ax> = 1.3770E-03 <bx> = 3.4644E-07 <ay> = 1.9412E-04 <by> = 4.8840E-08 other text <aax> = 1.3770E-03 <bbx> = 3.4644E-07

Hi list, I have some questions regarding 1) conversion of date + time characters to chron 2) formatting chron object printing Regarding (1), Gabor's Rnews 2004 4/1 article has been indispensible, but I often work with files where dates and times are contained in a single field. In this case, I would like to control input/output of chron objects when each observation of date and time is

Currently demo calls source with a hard coded max.deparse.length = 250 so you can't really see the demo properly in some cases. Note the [TRUNCATED] below. (1) It would be nice if demo passed max.deparse.length (and other args to source). (2) Also a larger max.deparse.length default would be nice to make it less likely one would have to set it in the first place. > R.version.string #

I have a string such as fileName<-"Agg.20.20.20-all-01". All I want to do is pull the "20.20.20" and the "all" as strings. Obviously, they aren't always those values. The "20.20.20" can be "30.30.30" but it's always after the . which is next to the second g in Agg and it's always the same length. The all might not always be

Hi everyone, I am starting learn to call C code from within R. So far, I've been trying toy problems to see if I can get them to work. One of the things I'd like to do is pass an arbitrary R function to C, evaluate the value in the C code using eval, and then return it. I also want to allow an arbitrary number of arguments to the function using "...". The code for my toy

Hi List, I've got a count matrix like this: [-11.9,-11] (-11,-10.2] (-10.2,-9.3] (-9.3,-8.44] [-11.9,-10.6] 0 0 0 0 (-10.6,-9.3] 0 0 0 0 (-9.3,-8.01] 0 0 0 0 (-8.01,-6.73] 0 0 0 0 I want to

A user reported that fsck was complaining about unresolved refs for some snapshots. You can reproduce this by doing mkfs.btrfs /dev/sdb mount /dev/sdb /mnt btrfs subvol snap /mnt/ /mnt/a btrfs subvol snap /mnt/ /mnt/b btrfs subvol del /mnt/a umount /mnt btrfsck /dev/sdb and you''d get this unresolved ref root 258 dir 256 index 2 namelen 1 name a error 600 because snapshot b has a dir

I'm running R 2.10.0 under Mac OS X 10.5.8; however, I don't think this is a Mac-specific problem. I have a very large (158,908 possible sentences, ca. 58 MB) plain text document d which I am trying to tokenize: t <- strapply(d, "\\w+", perl = T). I am encountering the following error: Error in base::gsub(pattern, rs, x, ...) : Calloc could not allocate (-1398215180 of

the content of th character vector (of length 1) is as follows: a <- "something2 ....pat1 name1 pat2 something2....pat1 name2 pat2....pat1 name3 pat2 " I would like to extract the character bewteen pat1 and pat2. That's to say, I would like to get a vecter of c("name1", "name2","name3"). What I did is use strsplit() twise. But I wonder if there
