In the context of calling R from another program (namely gretl, http://gretl.sourceforge.net ) I'm trying to understand the interactions of the R init file (corresponding to the environment variable RPROFILE) and the source() function. I'll illustrate my problem with the following simplified contrast implemented in the bash shell (with R 2.7.1). 1. Works fine: allin at myrtle:~/Rfoo$

Hi, I noticed this problem on my home desktop running FC4 and again on my laptop running FC5. Both have previously compiled and passed make check-all on 2.3.1 svn revisions from 10 days ago or so. On both these machines, make check-all is consistently failing (4 out of 4 attempts on the FC 4 desktop and 3 out of 3 on the FC 5 laptop) in the p-r-random-tests tests. This is with both default

Hello! I am trying to compute minimal time on some data like this: mt<-tapply(mrsh$time1,list(mrsh$var1,mrsh$var2),min): a b 145 1054800600 1054789800 340 1054804500 1054794600 349 1054820400 1054792800 55 1054800600 1054789200 57 1054814100 1054791000 78 1054822200 1054790400 843

Dear All,   I was wondering if you could help me with the following: I have the code:   tin <-0.5 tau <-24 output0 <-10 TIMELOW <-tin TIMEHIGH <-1*tau TIME1 <-c(seq(TIMELOW,TIMEHIGH, by = sign(TIMEHIGH-TIMELOW)*(tau-tin)/3))   then I would like to calculate:   cp1 <-output0*exp(-0.3*TIME1[1]) cp2 <-output0*exp(-0.3*TIME1[2]) cp3 <-output0*exp(-0.3*TIME1[3]) cp4

Hi, I have a vetor os dates with day and hour:minutes. > time1 <- c("03/08/08-11:00","03/08/08-11:10") > time1 <- as.Date(time1,"%d/%m/%y-%R") > summary(time1) Min. 1st Qu. Median Mean 3rd Qu. Max. "2008-08-03" "2008-08-03" "2008-08-03" "2008-08-03" "2008-08-03"

I thought this is a common question but rseek/google searches don't yield any relevant hit. I have a matrix of character strings, which are time stamps, > time.m[1:5,1:5] [,1] [,2] [,3] [,4] [,5] [1,] "08:00:20.799" "08:00:20.799" "08:00:20.799" "08:00:20.799" "08:00:20.799" [2,]

On the documentation page for DateTimeClasses, in the Examples section, there are the following two lines: format(.leap.seconds) # the leap seconds in your time zone print(.leap.seconds, tz = "PST8PDT") # and in Seattle's The second line (using print) seems to ignore the tz argument, and prints the dates in my time zone, while: format(.leap.seconds, tz =

Hello, One more question from the 'abusing R for blotting - particularly anally' department: How can I in the expression below make the '%~~%' show up as the aprrox-sign I want it to be?

Hi, I would like to merge two data frames. It is just that I want the merging to be done with some kind of a fuzzy criterion. Let me explain. My first data frame looks like this : ID1 time1 dt 1 2008-01-02 13:11 10 2 2008-01-02 14:20 20 3

Hello, I have an auto-scaled coordinate system and would like to add some clarifying lines to the graph - which ares supposed to meet the axis. >lines(c(0,time1,time1), c(1,1,0),lty=3) does what I want, BUT the second leg does not touch the x-axis since the auto-scaling of the y-axis does not start at'0' but slightly negative. I could now adjust the line length by 'trial and

In attempting to build R using rpmbuild --rebuild R-2.1.0-0.fdr.2.fc3.src.rpm on a fairly up-to-date RedHat 9 system (that is, with patches installed through May 1 2004), it failed at the make check-all step. The problem was reproducible by going into the tests directory and make test-Segfault The last lines of the saved file no-segfault.Rout.fail are > > ## c.POSIXct : > >

Hi r users, I have two data sets (X1, X2). For example, time1<-c( 0, 8, 15, 22, 43, 64, 85, 106, 127, 148, 169, 190 ,211 ) outpue1<-c(171 ,164 ,150 ,141 ,109 , 73 , 47 ,26 ,15 ,12 ,6 ,2 ,1 ) X1<-cbind(time1,outpue1) time2<-c( 0 ,8 ,15 , 22 ,43 , 64 ,85 ,106 ,148) output2<-c( 5 ,5 ,4 ,5 ,5 ,4 ,1 ,2 , 1 ) X2<-cbind(time2,output2) I want to

1) Why did you submit this *twice*, as PR#7826 and PR#7827? Please don't be so careless of the volunteers' time. 2) > print.POSIXct function (x, ...) { print(format(x, usetz = TRUE, ...), ...) invisible(x) } is definitely *not* implicated. (Use of ... in two places is correct.) 3) On FC3: > unusual_and_faults Error: protect(): protection stack overflow >

Further pursuing my curiosity to measure the efficiency of R/C++ interface, I conducted a simple matrix-vector multiplication test using .C and .Call functions in R. In each case, I measured the execution time in R, as well as inside the C++ function. Subtracting the two, I came up with a measure of overhead associated with each call. I assume that this overhead would be non-existent of the entire

To Whomever is Interested, I have spent several days searching the web, help files, the R wiki and the archives of this mailing list for a solution to this problem, but nonetheless I apologize in advance if I have missed something obvious. The problem is this; I have a 5-column data frame with about 4.2 million rows, and want to create a new (and hopefully much smaller) data frame that

R 2.6.1 on a Thinkpad T60 running up-to-date Gentoo: Despite the documentation, which says: 'strftime' is an alias for 'format.POSIXlt', and 'format.POSIXct' first converts to class '"POSIXlt"' by calling 'as.POSIXlt'. Note that only that conversion depends on the time zone. strftime fails on POSIXct objects: > foo <-
