Dear all, I have a large vector (lets call it myVector) and I want to plot its value with the logic below yaxis<-myVector[1] yaxis<-c(xaxis,mean(myvector[2:3]) yaxis<-c(xaxis,mean(myvector[4:8]) yaxis<c(xaxis,mean(myvector[9:16]) yaxis<c(xaxis,mean(myvector[17:32]) this has to stop when the new ..... yaxis<c(xaxis,mean(myvector[1024...

Yes, I am a newbie. I have a data.frame (MyTable) of 1445846 rows and 15 columns with character data. And a character vector (MyVector) of 473491 elements. I want simply to get a data.frame with the count of how many times each element of MyVector appears in MyTable. I've tried a loop with : for (i in 1 : length (myvector)) sum (MyTable== i) but it crashes my computer. I've also tried something like x <- 1 : le...

I encountered some problem when I try to SWIG to R some C++ modules. Here is the details. I got "myvector.i" and "myvector.h" as my two input files, the contends are: ---myvector.i----- %module myvector %{ #include "myvector.h" %} %include "std_vector.i" namespace std { %template(IntVector) vector<int>; %template(DoubleVector) vector<double>; };...

...to write a new class that reimplements the vector class. As a test of my overloading I decided to try and and call t.test on two vectors which were objects of my class rather than the default class. The overloaded length I wrote seems to work correctly. I used setMethod("length", "myvector", ...) setMethod("mean", "myvector", ...) setMethod("var", "myvector", ...) and created an object myv <- new("myvector",...) and when I called t.test(myv, myv) it first failed in the line mx <- mean(x) with the error that "x is...

I have two objects, one matrix and one vector. I want to use my vector to subset certain values out of my matrix. For example: I want to tell R, to select out all rows in myMatrix into a new myMatrix2 IF that corresponding row is less than a 0.5 in myVector. So: myMatrix = a matrix of 8000 by 20 myVector = vector of 8000 myMatrix2 = a matrix of < 8000 by 20 (based on selection criteria in myVector) I hope this makes sense..

Hello, Let's assume I have a vector of integers : > myvector <- c(1, 2, 3, 2, 1, 3, 5) My purpose is to obtain the cumulative distribution of these numerical data, i.e. something like : value nb_occur. <=1 2 <=2 4 <=3 6 <=4 6 <=5 7 For this, I create a table with ; > mytable <- table(myvector) 1 2 3 5 2 2 2 1 Ho...

Hello, I have an expression that I want to substitute for something else. myvector<-c("ajkhfkiuwe","Variable(kg/min)") if I use the following code to extract "variable(kg/min)" and substitute it for "va" gsub(myvector[grep("var", myvector, ignore=T)], "va", myvector) grep identifies the element of the vector that...

Dear all, I have a vector with number that some of them are part of the   seq(1,800,4). How can I check which of the numbers belong to the seq(1,800,4)   LEt's say that is called myvector the vector with the numbers. Is there in R something like this? is.member(myvector,seq(1,800,4))   I would like to thank you in advance for your help   B.R Alex [[alternative HTML version deleted]]

Dear People, I have got the following example for a vector and the index of the TRUE element: Myvector <- c(FALSE,FALSE,FALSE,FALSE,FALSE,FALSE,FALSE,TRUE) which(Myvector) Now I would like to find out the same for a list: Mylist <- list(FALSE,FALSE,FALSE,FALSE,FALSE,FALSE,FALSE,TRUE) ... Does anyone know how to do this? Thank you very much in advance, Marion [[alternative HTML version d...

Hello dear R-helpers, I haven't been able to figure out of find a solution in the R-help archives about how to delete all the characters contained in groups of parenthesis. I have a vector that looks more or less like this: myvector<-c("something (80 km/h, sd) & more (6 kg/L,sd)", "somethingelse (48 m/s, sd) & moretoo (50g/L , sd)") I want to extract all the strings that are not contained in parenthesis, the goal would be to obtain the following new vector: subvector<-c("something &...

Hi, Is there a way to do it? For example I have the following vector: > print(myvector) > [1] -295.8045 -295.8045 -295.8045 -295.8045 -325.4754 -295.8045 -295.8045 [8] -295.8045 -413.2099 -295.8045 I want it to return -295.8045, which occur most often. - Gundala Viswanath Jakarta - Indonesia

Hi, Suppose I have a vector in real number (x1, x2, x3, x4, x5, x6) My question is how I can get x5*x3*x1 + x6*x4*x2 ? Thanks a lot. Dot. -- View this message in context: http://www.nabble.com/how-can-I-do-this-sum--tp18931693p18931693.html Sent from the R help mailing list archive at Nabble.com.

Sounds simple but haven't been able to find it in docs: is it possible to sort a vector using a user-defined comparison function? Seems it must be, but "sort" doesn't seem to provide that option, nor does "order" sfaics -- View this message in context: http://www.nabble.com/custom-sort--tp23770565p23770565.html Sent from the R help mailing list archive at Nabble.com.

hello everybody, i have got a question about lists: i have got the following commands: mylist <- list("v1"=c(1,2,2,1),"v2"=c(2,2,2,1),"v3"=c(1,1,1,1)) myvector <- c(100,10000,1000000) now i would like to multiply each element of the list with the corresponding element of the vector, that is to say: v1*100 v2*10000 v3*1000000 i only could think of lapply which can only be used to multiply each element of the list with the same number, i think. thank y...

Hello, i would like to ask you another question. Is exist anymethod to vectors that tells me the last element?That is to say,I have a vector, I want to return the position of last element.
