...oothing routines such as panel.lowess(), because the smoothed values are on the horizontal axis, not the vertical axis. Before I start looking at and modifying the R code that makes up the relevant routines, I wonder if any reader has already developed R routines for this purpose? -- Michael Prager, Ph.D. NOAA Beaufort Laboratory Beaufort, North Carolina 28516 http://shrimp.ccfhrb.noaa.gov/~mprager/ ***

...Looking to print, neither the section on "model formula" on p.56 of MASS nor the section surrounding the above example explains the notation, nor could I find it in Dalgaard's book, nor in Maindonald and Braun. This seems too nice a feature to keep hidden in plain sight. -- Mike Prager, NOAA, Beaufort, NC * Opinions expressed are personal and not represented otherwise. * Any use of tradenames does not constitute a NOAA endorsement.

...rrect sequence? 1. save.image() to save the current workspace as .Rdata in the current working directory. 2. rm(list=ls()) to remove everything from the workspace. 3. setcwd("xxx") to set the new working directory. 4. load(".Rdata") to load the new workspace. -- Michael Prager, Ph.D. NOAA Center for Coastal Fisheries and Habitat Research Beaufort, North Carolina 28516 http://shrimp.ccfhrb.noaa.gov/~mprager/

...issue is that a line of text takes up a smaller fraction of the total Y span of the plotting region as the window gets larger. It seems this can be done with grid graphics, but although I plan to learn grid, I am hoping that for now, I can do this work with traditional graphics.

A minor inconvenience in updating an R installation is remembering which packages were installed previously. Has anyone written a script to inspect a previous installation, then get & install the same packages into the new installation? -- Michael Prager NOAA Center for Coastal Fisheries and Habitat Research Beaufort, North Carolina 28516 Opinions expressed are personal, not official.

...omewhere that locations on plots (in my case, arguments x and y for legend()) can be specified in several scales besides the usual data scale. I would like to set x and y as proportions of total plot size or something similar.

Dear List, Is there a possibility to change the font-face for a part of the title of a plot? For example I have the following... plot(nirs, type="l", xlab="Wellenl?nge [nm]", col="darkslategray", main = "Spektrum Deschampsia caespitosa") ...and I would like to change the part of the title-string "Deschampsia caespitosa" to italics?

...view -- one who has never written a parser nor taken a course in compilers -- what is needed is the nonexistent function "value" usable in plotmath expressions to produce the value of its argument, as plot(1:3, 1:3, main = ~ a == value(aa)) How can this be done?

...ironment (workspace) was loaded (and to which it will, by default, be saved)? This seems identical with the current directory, so in any given session it is not too difficult to find out by other means. But for several reasons I would like to find this out from within R.

I need help with replacing NaN with zero (the value '0') in my dataset. The reason is that I can't get it to graph because of the NaN in the dataset. I have tried: data[is.nan(data)] <- 0 that others have suggested in the help archives but this does nothing so I am not sure what I am doing wrong. Thanks in advance for your help.
