[R] IDE with table/matrix preview

I know there are several threads about IDEs for R. I've tried Tinn-R, but I am looking for an IDE (win) with a preview function that shows me the variables and the table/matrix etc. when klicking. (comparable to Matlab). Does an IDE like this exist or can't IDEs give this functionality in R?

[R] optimized value worse than starting Value

Dear all, I'm optimizing a relatively simple function. Using optimize the optimized parameter value is worse than the starting. why? f<-function(delta,P,U){ minimiz<-P+delta*U x<-minimiz[1] y<-minimiz[2] z<-100*(y-x^2)^2+(1-x)^2 return(z) } result<-optimize(f, interval=c(

[R] Strange behavior of interval values in optimize()

Hi all, I'm using optimize() to find the minimum of the following function f, and minimize it (without f<-function(delta,P,U){ minimiz<-P+delta*U x<-minimiz[1] y<-minimiz[2] z<-100*(y-x^2)^2+(1-x)^2 return(z) } result<-optimize(f, interval=c(-1, 1), P=c(0.99,1.01), U=c
