Dear R users, has anybody made an attempt to create the soil texture triangle graph in R? For an example see here: http://www.teachingkate.org/images/soiltria.gif I would like to get the lines in black and texture labels in gray to allow for plotting my texture results on top. Any examples or suggestions are very welcome! Thanks in advance, Sander. --

Hi there, (sorry Martin, ich habe den falschen Empfaenger erwischt :-( ) Is there a function in the base package or elsewhere which returns TRUE and not NA, even if NA is involved: (I did not find in the help system :-( ) if ( x==something & !is.na(something)) or if ( x==something & !is.na(x==something)) If "something" is complicated, a function would be handy. Thanks

Hi, Using help under help.start() is working fine (html) Q1: using > ?solve results in the message "sh: ~/R/tmp/R4f32S1cfb: cannot open" displayed in the XEmacs buffer "help[R](solve)". BUT there exists a file R.R4f32S167e in that directory. (not quite the same name). Does the "sh: " prefix suggest that the shell "sh" is run, although my

Hi there, I am interested in the inner workings of wilcox.test: > wilcox.test function (x, ...) UseMethod("wilcox.test") <environment: namespace:stats> how can I get at the code, if it is R-code?

Hi, This may belong more to r-develop, but general discussion may be useful (for the how many-th time ?) seq(2,5,-2) seq(5,2,2) both result in Error in seq.default(2, 5, -2) : wrong sign in 'by' argument But often, if not always, mathematicians and programmers want a behaviour e.g. in for loops, where this statement results in an empty statement, that is for (ii in seq(2,5,-2))

Hi, I would like to know if it is possible to get printed output while a loop is taking place. Example: for(i in 1:10){ print(i) some long process } This will print the values of i only after the loop is finished, what I would like is to see them when the process enters the i-th iteration to keep track of how the program is running. Thank you, Gilda

I am running R-1.3.0 on Solaris 8: Under Solaris I do setenv dendro_us hoffmann echo $dendro_us gives back: hoffmann which is correct.

Dear all, I would like to multiply two matrixes with the different dimension column by column. Let make an example: If I have two matrixes "X" and "Y"as follow: X<- matrix(1:12, nrow=4, ncol=3, dimnames=list(c("A","B","C","D"), c("stage1","stage2","stage3"))) Y<- matrix(1:28, nrow=4, ncol=7,

Hi, I am trying to use sub, regexpr on expressions like log(D) ~ log(N)+I(log(N)^2)+log(t) being a model specification. The aim is to produce: "ln D ~ ln N + ln^2 N + ln t" The variable names N, t may change, the number of terms too. I succeded only partially, help on regular expressions is hard to understand for me, examples on my case are rare. The help page on R-help
