Is there a way to call a function, and explicitly set an argument to 'not specified'? My situation is the following. I have a function which passes on most of its arguments to another function. The second function, myfun2, serializes all arguments and is out of my control. myfun <- function(...){ return(myfun2(...)); } now, the value for arguments of myfun are stored in variables.

Hi I am relatively new to R and am trying to figure out to plot 3d scatter plot using defined colors based on x-axis and y-axis values. Right now in the code below, I assign colors based on certain values in the names of the x-axis. Now if I want to extend the condition to assign a color based on the names of both x-axis and y-axis values, what should I be doing? Any help or ideas would be

Hi, I was trying to make a density plot with 13 samples. To distinguish each sample, it would be good if each color is as different as possible from the other colors. I could use the built in function, but that does not do more than 8 colors and then goes back to recycling the cols. If I use a palette, then it is really difficult to distinguish between the colors. So, is there a way that I can

R-help, I'm trying to read a data file with plenty of columns. I just need the first 5 but it doe not work by doing something like: > mycols <- rep(NULL, 430) ; mycols[c(1:4)] <- NA > read.table(myfile, skip=2, colClasses=mycols) Any suggestions? Thanks in advance

Hello, I have a data frame which looks like > head(d) a1 a2 n j col 1 1 1 88341002 11 #E7E7E7 2 1 2 25094882 11 #E7E7E7 3 1 3 16916246 11 #E7E7E7 4 1 4 14289229 11 #E7E7E7 5 1 5 11945929 11 #E7E7E7 6 1 6 8401235 11 #E7E7E7 The values in 'j' run from 1 to 11. I would like to plot the point (a1,a2) with color given by j I tried mi <-

How can I right justify the right-axis tick values? They appear in the example below as left-justified. I have tried several different ways and all fail in different ways. The example below creates the right axis tick value with no attempt at adjustment. alternates I have tried are 1. formatting the values. This doesn't work because they are in a proportional font and the blanks are too

Hi, I was trying to get an image/pdf of a sequence of colors in the order given. For example: myCols <- c('#0000BF','#0000BF','#0000FF','#0000FF','#0000BF','#0000FF') I'd like to make a strip of colors as they appear in the order above and save it as a pdf file. Is there a function in the base package (or some other package) to do this?

Just wondering: it appears that "srt" does not accept a vector of values, just a single value. I ended up using tapply() as the following code snippet shows, so it's not a major problem. I was justa little surprised that this argument (srt) differs from things like "labels," "lty," "col," and so on, all of which accept (and recycle as needed

Dear R gurus, I want to wrap labels that are too long for a plot. I have looked at strsplit(), substr(), nchar(), and strwrap(). I think it's some combination but I'm having difficulty trying to figure out the right combo. I think I need to create some new matrix containing the labels already split, though I'm not sure if maybe there is a quick and dirty way to address this

Rotated text for axis labels should be possible with one of par(srt=90) axis(1,at,labels) par(srt=0) or axis(1,at,labels,srt=90) (or similar with crt instead of srt) None of these works in pre0.65 or in 0.64.2 _ platform sparc-sun-solaris2.7 arch sparc os solaris2.7 system sparc,

Dear R-users moving from Splus to R (under Windows), I notice that command "srt" within a plot in the original Splus code is ignored by R. For example, if a plot something and then include the line of code axis(1, at=Time, labels=Text, srt=45, adj=1) the srt=45 command within the axis() command fails to draw Text at 45 degrees on the x-axis in R but it works properly in Splus. I will

Full_Name: Emmanuel Paradis Version: 2.4.0 OS: Linux Submission from: (NULL) (193.49.41.124) Adding text to a plot makes R freeze if 'srt' is given a very small negative value, eg: plot(1, type = "n") text(1, 1, "some text....", srt = -1e-8) But if 'srt = -1e-6' (or smaller) or 'srt = -1e-19' (or greater), this works. This seems to be OS-dependent:

I have a data frame. And I'd like to subset according to rownames. subset(mydataframe, rownames(mydataframe) == myrow, select = mycols) it turned out that "myrow" cannot be a vector.

Hi, This is not a bug, but an enhancement suggestion. "strwidth" only gives the width of the text according to the x-axis user coordinates, and similarly for "strheight". Even if the par setting "srt" is changed to rotate the text, the resulting width (resp. height) is in terms of the non-rotated text. Currently, if I want to know how much space to leave for
