Hi everyone, I have a matrix containing color values of an image same as following, [1,] "#444444" "#444444" "#434343" "#404040" "#3D3D3D" "#3D3D3D" "#3E3E3E" [2,] "#414141" "#414141" "#414141" "#404040" "#3F3F3F" "#3F3F3F" "#3F3F3F" [3,] "#3E3E3E" "#3E3E3E" "#3F3F3F" "#404040" "#404040" &qu...

...uot;[.raster"() is coded; when subsetting as a vector, which str() relies on, "[.raster"() still returns a matrix-like object, e.g. > img <- as.raster(1:25, max=25, nrow=5, ncol=5); > img[1:2] [,1] [,2] [,3] [,4] [,5] [1,] "#0A0A0A" "#3D3D3D" "#707070" "#A3A3A3" "#D6D6D6" [2,] "#141414" "#474747" "#7A7A7A" "#ADADAD" "#E0E0E0" compare with: > as.matrix(img)[1:2] [1] "#0A0A0A" "#3D3D3D" The easy but incomplete fix is to do: st...

Hi I am running FC5 with nut coming from the fc5 extras repositories. I am trying to configure a Gamatronic D-Compact ups. The cable that came with the ups has a serial connector on one end and a usb on the other. cat /proc/bus/usb/devices produces T: Bus=01 Lev=01 Prnt=01 Port=01 Cnt=01 Dev#= 4 Spd=1.5 MxCh= 0 D: Ver= 1.10 Cls=00(>ifc ) Sub=00 Prot=00 MxPS= 8 #Cfgs= 1 P:

Hi Everyone, I am stuck with a simple problem. Suppose I have a vector x, and I want to calculate y[i]=3Dx[i+1]-x[i], it is very easy. I just need to write y<-x[2:length(x)]-x[1:length(x)-1]. Now if I know y, and want to know the vector x defined by x[i]=3Dx[i-1]+y[i-1] for all i, how can I do this without a loop? Thanks, Geoffrey PS. Sorry if you see a duplicate message. The previous
