I have seen a couple of posts about color schemes like those at the ColorBrewer site. Most recently: http://geography.uoregon.edu/datagraphics/color_scales.htm These color schemes can work very well for regions (bars, polygons, images, etc.) but are not very suitable for points and/or lines. Is anyone aware of research/suggestions for a color scheme to use for scatter plots? I've looked at

This mailing list truly is amazing. Thank you so much for all the help! I feel a little strange asking something that "simple" again, but I wasn't able to find it in the help... Is there a way to tell R how to display numbers (double)? How many numbers after the decimal point, etc... Thanks again, folks and have a nice New Years Eve! Dax

all/any coerce their arguments to logical (if possible). I've added a warning in R-devel if coercion is from something other than integer. This arose because it is easy to make a slip and write all(X) > 0 rather than all(X > 0): thanks to Bill Dunlap for bringing that to my attention. However, it has been useful in detecting quite a few other things: - indices which had been made

These are some points stimulated by reading about C history (and related in their implementation). 1) On some platforms > as.integer("0xA") [1] 10 but not all (not on Solaris nor Windows). We do not define what is allowed, and rely on the OS's implementation of strtod (yes, not strtol). It seems that glibc does allow hex: C99 mandates it but C89 seems not to allow it. I

We say in ?points that 'pch' (among others) can be set to NA for omitting a point. While this works in cases where there's at least one point left to draw, it fails in a simple case like this : > plot(1, pch = NA) Error in plot.xy(xy.coords(x, y), type = type, pch = pch, col = col, bg = bg, : invalid plotting symbol Both in R-patched or R-devel. A simple workaround {hinting

This only happens if 'file' is a text connection, and is the expected behaviour in that case: you cannot capture an incomplete line to a text connection. There seems no reason to break the documented behaviour in other cases to change something that you consider to a bug when file=NULL and the user does not produce complete output. It would be possible to make use of isIncomplete()

R 1.4.0 ?stars has scale: logical flag: if `TRUE', the columns of the data matrix are scaled independently so that the maximum value in each column is 1 and the minimum is 0. If `FALSE', the presumption is that the data have been scaled by some other algorithm to the range [0,1]. but the code has if (scale) { x <- sweep(x, 2,

[This turned into a bug report which will go to r-devel, so I have taken it off r-help.] Bugs reported here: (1) formatC's help page need some clarification. (2) formatC needs to treat modes "double" and "real" as equivalent. (3) format's help page or (preferably) format needs correction re the meaning of `digits' On Sun, 28 Feb 1999, Martin Maechler wrote:

I have tightened the tolerances in glm.control in R-devel (aka 1.8.0 Under Development) from epsilon = 1e-4 to 1e-8, and increases maxit from 10 to 25. Normally the effect is to do one more iteration and get more accurate results. However, in cases of partial separation several more iterations will be done and it will be clearer from the results which parameters are converging and which are

Very few computer programs do that. You cannot `require' two digits by options(digits=2): ?options says digits: controls the number of digits to print when print- ing numeric values. It is a

Is there an R function that automatically writes all input and output to a file? I would at least like it to log all the commands I enter, and to preferably also write the standard output to the file as well as to the screen. (The ideal would be to write the input to one file and both the input and output to another file.) I tried R2HTML for this, but I could not get it to work consistently. I am

I don't think the buglets are wrong. You don't drop length 0 dimensions. If you did, the object would be of the wrong length.

Hi , When I sort a vector of POSIXct values in R-2.3.0 and R-2.3.1, I get a vector of numeric values and this gets some of my code to crash (class object creation). Is that a R bug? In the mean time. I'll try to override the sort function for the POSIXct objects. Thanks, Patrick Gu?vel Head of quantitative research for electronic trading This message and any attachments (the
