Hi R list, I like the default ticks that are set up using grid.xaxis() or grid.yaxis() with no arguments. Finding good values for the 'at' argument is usually not a trivial task; the default behavior of these functions seems to work well. The problem with this strategy is that I cannot figure out how to "recover" the positions of these ticks when...

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[1024:2048]) will not find the correspondent number of elements, either wise it will stop with an...

Hi, I try to create a vertical line in my plot, which has a xaxis comprising time formated data. This is what I tried: ---------------- y<-152833 x<-strptime(y, format="%H%M%S") abline(v=x, col="red") ---------------- for some reason, it doesn't work and no error msg is displayed... I hope someone can tell me what I do wrong,...

>library(ggplot2) >(p<- qplot(mpg, wt, data=mtcars)) What I am doing is to set color of the ticks to hide them. >grid.gedit(gPath("xaxis", "ticks"), gp=gpar(col="white")) It should be a better way to achieve the purpose. Thanks.

Hello there, I would like to plot a graph with the x axis's label displayed at a 45 angle to the x axis instead of horizontal to it as the label is very long. What should I do? Thank you for your help in advance Lisa Wang Princess Margaret Hospital Toronto, Ca

Hello, I have been trying to plot correctly a graph for 2 month now, with no success.I want to put a grid, adjusted on the X axis tickers.

Hi, I am trying to use an R function over a column of data I have in my excel spreadsheet. I do the following:- 1) assign an object (calling it xaxis) to the data by typing in =Rput("xaxis",a1:a10), where my data is shown in cells a1:a10 Now I wish to arrive at the mean of these numbers and am doing the following in another cell:- =Rapply("mean","xaxis") This does not work.

Dear All, Apologies for this simple question and thanks in advance for any help given. Suppose I wanted to plot 1 million observations and produce the command plot(rnorm(1000000)) The labels of the xaxis are 0, e+00 2 e+05 etc. These are clearly not very attractive (The plots are for a PhD. thesis). I would like the axes to be 0,2,4,6,8,10 with a *10^5 on the right hand side. Is there a simple command for this? Best Wishes Roger

Hi! I'd like to plot things with axes going from the highest to the lowest value, so that e.g. high values on the xaxis are plotted to the left and low values to the right. Could anyone tell me how this is done? I couldn't find anything in the documentation. Thanks a lot! Silli
