[R] Graph many points without hiding some

ve this through automatically iterating my data as above, using transparent symbols, or something else? Is there some other way of solving this issue that I haven't thought of? Thankyou, Samuel Dennis [[alternative HTML version deleted]] __ R-hel

Re: [R] how do i plot this "hist"?

To superimpose anything onto a barplot you just need to know the x axis locations of the bars, then everything behaves as expected. You can find this by writing the barplot to an object, ie: bp <- barplot(c(1:5),beside=TRUE) bp is now a matrix containing the actual x axis locations of the bars (i

Re: [R] help cannot put multiple chart Stacked Bar (from PerformanceAnalysis library) in a single plot

I am unfamiliar with the chart.StackedBar function, but since barplot works as expected I thought I'd check that you do know you can obtain stacked bar charts using barplot also? (beside = FALSE). On 10 November 2010 09:41, patrick nguyen wrote: > Hi > > > I'm having problems displaying multiple

Re: [R] Barplot + plot same scale

lot(c(10,12,18)) lines(midpts,c(0,2,3), t="l") This will make your barplot, save the centres of the bars to a variable called "midpts", and then plot a line over those bars. I hope this helps. Samuel Dennis 2010/1/8 Mister Vanhalen : > Hello, > > I would like

Re: [R] Optimise parameter of a generic function

Typical, spotted a very stupid typo in my code after posting, and when corrected I have solved my own problem. Sorry for bothering everyone. Line below should have read: optimise(f = nbinopt, interval = c(0,100), maximum=FALSE, tol=0.01) Samuel Dennis wrote: > > optimise(f = nbin063, in

[R] Optimise parameter of a generic function

I would like to know how to determine the best value of a particular parameter in a generic function. My function is: nbin <- function(k,Dt) { R <- Dt / (k + Dt) q <- (k + Dt) / k Pt <- c(0:7) for (r in c(0:7)) { Pt[r+1] <- (factorial(k+r-1)/(factorial(r)*factorial(k-1)))*((R^r)/(q^k)) } Pt } Th
