Re: [R] tcl/tk problem with tklistbox,the " " character and Rcmdr.

Hi Vincent, This is probably because Rcmdr redefine the tclvalue command (check the message frame of the Rcmdr window). You can try: tcltk::tclvalue(tkget(levels.list2,"4")) HTH, Yves Le 20/11/2012 11:25, vincent guyader a écrit : > I everyone, > > i have a little problem with tklistbox,t

Re: [R] How to compute "yaxp" and "usr" without plotting ?

Thank you very much Greg, This was helpful. With yaxs="r" I can easily obtain the Y-axis labels with : rg <- range(y) + 0.04 * diff(range(y)) * c(-1, 1) pt <- pretty(y) axTicks(side=2, usr=c(0, 1, rg), axp=c(min(pt), max(pt[pt <= max(rg)

[R] How to compute "yaxp" and "usr" without plotting ?

Dear all, I'd like to know how I could compute the parameters "yaxp" and (the y components of) "usr" without having to plot the data first. Note that "ylim" is /a priori/ fixed. The aim is to automatically adjust the parameter "mgp" without having to make the plot twice. Then, with "yaxp" an

Re: [R] force apply not to drop the dimensions of FUN results ?

Thank you very much Claudia, That (the first form) works perfectly. Easily made generic using head and tail on the dim attribute. All the best, Yves Claudia Beleites a écrit : Dear Yves, You may not need to do more than set the dim attribute correctly: dim (test) <- c (dim (myArray) [c (3

[R] force apply not to drop the dimensions of FUN results ?

ssing this behaviour ? (unfortunately my function seems not suitable for a vectorization using sweep) Alternatively, a method to recover the wished array dimensions afterward would be also acceptable. Many thanks in advance. Yves -- ------- Yve

Re: [R] calculate area between intersecting polygons

Dear Jonas, I already had to deal with such an issue. Your can use the joinPolys function from the package PBSmapping, with "INT" as operation. The maptools package has functions SpatialPolygons2PolySet and PolySet2SpatialPolygons to switch between formats suitable for sp or PBSmapping. Hope thi
