similar to: followup: lookup function for density(...) objects

Hi, I cannot find a 'vectorized' solution to this 'for loop' kind of problem. Do you see a vectorized, fast-running solution? Objective: Take the value of X at each timepoint and calculate the corresponding value of Y. Leading 0's and all 1's for X are assigned to Y; otherwise Y is incremented by the number of 0's adjacent to the last 1. The frequency and

Hi, Is there a faster way to do this? It takes forever, even on a moderately sized dataset. n <- dim(dsn)[1] dsn2 <- dsn[order(-dsn$xhat),] dsn2[1, "cumx"] <- dsn2[1, "xhat"] for (i in 2:n) { dsn2[i, "cumx"] <- dsn2[i - 1, "cumx"] + dsn2[i, "xhat"] } [[alternative HTML version deleted]]

Hi folks: Is there a lookup function that returns the variate given the cumulative probability for an object returned by the density(...) function? > mydata _ as.vector(mymatrix) > mydata.density _ density(mydata) > mydata.p80 _ lookup(mydata.density, p=0.8) # is there any function to accomplish this task? Thanks. Rajiv. -------- Rajiv Prasad, Postdoctoral Research Associate,

Hi folks: I'm trying to compile R-2.0.0 on my Alpha (164SX; alphapca56-unknown-linux-gnu) running RedHat Linux 7.2 with gcc3.4.1.

Hi folks: I used to load a DLL fine up until R 1.5.1. The same DLL dyn.loaded under R 1.6.2 prints the following warning message: > dyn.load("C:/Rajiv/Bin/rpdate.dll") Warning message: DLL attempted to change FPU control word from 8001f to 9001f > Any indication as to what the warning means, and whether I should be concerned about it? The DLL is made from a pure C code,

Thanks, Prof. Ripley. I downloaded the new admin.R and used that in place of one in R-2.0.0 build directory. The compile went fine. So, for the record, R-2.0.0 + Prof. Ripley's fixed admin.R compiles fine on "alphapca56-unknown-linux-gnu". ---- [rajiv@localhost rajiv]$ R R : Copyright 2004, The R Foundation for Statistical Computing Version 2.0.0 (2004-10-04), ISBN

Thanks, Peter, and Prof. Ripley. My efforts last night was mostly futile except that it told me about the embedded newline in Built field. Prof. Ripley: how do I get your fixes? Can I just download R-2.0.0-patched? Rajiv -------- Rajiv Prasad Scientist, Hydrology Group Pacific Northwest National Laboratory, P.O.

Hi folks: This may be a stupid question, but I cannot seem to find a way to tell readBin that I want to read 2-byte integers from the connection. The input file is 150,720 bytes long containing 75,360 short (2-byte) integers. But specifying "integer" or "int" for what in readBin only returns me a vector of length 37680, leading me to believe that sizeof(integer) or

Hi folks: Any idea when the density and angle arguments to polygon() are to be implemented? Or is there another way to achieve hatching fill patterns? TIA.

Hi folks: I am just beginning to try and use R from my own C programs. Platform is Windows2000, compiler Visual C++ 6.0. I built the import library R.lib from R.dll using the VC LIB.exe program. Here is a simple code I am trying to compile and run (no C++, VC++ is instructed to treat it strictly as C): #include "R.h" #include "Rinternals.h" int main(void) { int i; char

Hi folks: I think I'm having problems with figuring this one out: test1 <- function() { n <- 2 for(i in 1:n) { cat(paste("i =", i, "\n")); flush.console() n <- 5 # version 1 #n <<- 5 # version 2 #assign("n", 5, envir = environment(test1)) # version 3 } } I need the for(.) loop to run (say) n=5 times within the

Hi, I have two Fedora box and rsync running on both systems. One system ip is 192.168.1.110 and the other is 192.168.1.71. I run manually for the following commands in both systems. my problem is whenever run it asking the user passwd and i cannot run the same automatically using crontab. My question is how to avoid the passwd option... rsync -aPrv rsync://192.168.1.110/detailing/

Hi folks: I have a feeling this must be a FAQ, but I did not find the answer in R Installation and Administration manual.
