[R] Drawing paths through a grid

I would like to draw a set of points that are equally spaced in a 2-D grid. Then I would like to draw lines that illustrate different directed paths through subsets of points. Imagine that the points correspond to booths in a conference center, and I want to show the various paths people took to

[R] Possible to write text inside a bar of a barplot?

How can I write text inside a bar of a barplot? I tried using text(), but I am only able to specify the numeric y-coordinate. The different columns of my barplot correspond to factors and not numbers, so I don't know how to access the horizontal positions of the bars. I tried fiddling with

Re: [R] Possible to write text inside a bar of a barplot?

Thanks for the replies! The answer is that barplot() returns the x coordinates of the bars. On Fri, Jan 15, 2010 at 12:01 PM, Rex C. Eastbourne rex.eastbou...@gmail.com wrote: How can I write text inside a bar of a barplot? I tried using text(), but I am only able to specify the numeric y

[R] Barchart bar lengths not proportionate

When I use barchart (with default formatting options), I get bars whose lengths/heights are not proportional to their value. For example: http://drop.io/wbagm6s/asset/capture-png Many of the values in this chart are 1; however, because the blue bars extend to the left of the 0 tick mark, those

xlim()/ylim() argument. Look at the follwing code: require(lattice) da - expand.grid(A=c(a,b), x=1:4) da$y - c(1,5,6,3,2,0,6,0) barchart(y~x|A, data=da, horizontal=FALSE) barchart(y~x|A, data=da, horizontal=FALSE, ylim=c(0, 1.05*max(da$y))) At your disposal. Walmes. Rex C

I am encountering problems using the png() function to save around 20 charts to separate files. My script is conceptually structured as follows: ### script png(Image %03d.png) # the following are calls to user-defined functions I wrote that call plot, barchart, etc. with special arguments.
