Is it possible to use the "integrate" function when it depends on a parameter? in other words can i get something like f(y) = integrate (g(x,y))? If not, how else can I get that? thanks in advance BL -- View this message in context: http://r.789695.n4.nabble.com/integral-depending-on-a-parameter-tp3722185p3722185.html Sent from the R help mailing list archive at Nabble.com.

Hi all I have a function of log defined by y = log(1- exp(-a)), when exp(-a) is greater, 1, it produce NaN. How can I remove this in R? [[alternative HTML version deleted]]

Hi group, I imported 16 data frames using the function "list.files" temp <- list.files(path="...........") myfiles = lapply(temp, read.table,sep = "") Now I have 16 data set imported in R window. I want to combine them by row and tried some thing like (Here I am considering only 20 columns) for(i in 1:16){ data<- cbind(myfiles[[i]][,1:20]) } but it

Hello R community, following is my code and it shows error, can some one fix this error and explain why this occurs? gibbs <-function(m,n, theta = 0, lambda = 1){ alpha <- 1.5 beta <- 1.5 gamma <- 1.5 x<- array(0,c(m+1, 3)) x[1,1] <- theta x[1,2] <- lambda x[1,3]<- n for(t in 2:m+1){ x[t,1] <- rbinom(x[t-1,3], 1, x[t-1,1])

Hi R community, I have some data set and construct the likelihood as follows likelihood <- function(alpha,beta){ lh<-1 d<-0 p<-0 k<-NULL data<-read.table("epidemic.txt",header = TRUE) attach(data, warn.conflicts = F) k <-which(inftime==1) d <- (sqrt((x-x[k])^2+(y-y[k])^2))^(-beta) p<-1 - exp(-alpha*d) for(i in 1:100){

I'd appreciate it if you'd keep on list for the archives. That said, I think this function does what you were hoping for.

Dear R users, I've two questions: 1) Does anybody have a clue how to convert pixel from a jpeg graphic (e.g. something like a square of 100x100 pxs) into axis coordinate values in R? / //2)// Is there any possibility to extend the locator function in a way that //locator( ) outputs all coordinates from a plot at once, without clicking on the graph? Thanks for any hints. Regards, P.

Hi all, Can some one tell me the difference between the following two formulas? 1. epiG.rf <-randomForest(gamma~.,data=data, na.action = na.fail,ntree = 300,xtest = NULL, ytest = NULL,replace = T, proximity =F) 2.epiG.rf <-randomForest(gamma~.,data=data, na.action = na.fail,ntree = 300,xtest = NULL, ytest = NULL,replace = T, proximity =F) [[alternative HTML version deleted]]

Hi all, I have a set of elements (1, 1, 0,1,1,0,1,0,1,1) with ten elements. I have to construct the permutation matrix of this set which is of the size 10 by 2^10.

Hi all, I have the following code, When I run the code, it never terminate this is because of the while loop i am using. In general, if you need a loop for which you don't know in advance how many iterations there will be, you can use the `while' statement so here too i don't know the number how many iterations are there. So Can some one suggest me whats going on? I am using the
