search for: xsample

Dear R-developers community, I have the following generic: setGeneric( name="newsample", def=function(x,y,z,a,b,c,...){standardGeneric("newsample")} And I can build several methods for this generic. One useful thing is to use "newsample" with only one of the 6 arguments listed. At the moment this is what I do: setMethod(

Dear R-users, i try to solve to following linear programm in R 0 * x_1 + 2/3 * x_2 + 1/3 * x_3 + 1/3 * x_4 = 0.3 x_1 + x_2 + x_3 + x_4 = 1 x_1, x_2, x_3, x_4 > 0, x_1, x_2, x_3, x_4 < 1 as you can see i have no objective function here besides that i use the following code. library(lpSolve) f.obj<-c(1,1,1,1) f.con<-matrix(c(0,2/3,1/3,1/3, 1,1,1,1,

I am trying to plot a lognormal density curve on top of an existing histogram. Can anybody suggest a simple way to do this? Even if someone could just explain how to plot a regular normal density curve on top of an existing histogram, it would be a big help. Also, is there some way to search through the R-help archives other than simple browsing? Thank you so much. Your help and time is greatly

Dear All, I am new to R and slowly learning how to use the system. The following code is an exercise I was trying. The intent is to generate 10 random samples of size 5 from a vector with integers 1:10 and 2 missing values. I then want to generate a matrix, for each sample which shows the frequency of missing values (NA) in each sample. My solution, using sapply is at the end. If anyone has the
