Hi all, I just cannot think of how to do it: I want to take the first variable (column) of a data frame and regress it against all other variables. bla <- function (dat) { reg <- lm(whateverthefirstofthevariablenamesis ~., data=dat) return(reg) } What kind of function do I have to take instead of the whateverthefirstofthevariablenamesis, eval(), substitute(), get(), ... to

I am trying, without success, to find out how to formulate correctly the parameters of "eval". My code snippet looks like: proutside <- function(txt) { cat("\n",txt,"\n"); print(eval(parse(text = txt))) } vari <- function(Ob) { prininside <- function(txt) { cat("\n",txt,"\n"); print(eval(parse(text = txt))) }

Hi everyone, Being new to the crowd of R users I am wondering what the equivalent of attach("/home/bla/hoffmann/R/.RData",2) (S style) is in R. What I want is a split of .RData repositories. One in a central place where I keep functions and interesting stuff important for all work I am doing, an several others which contain stuff of an dividual project only. When I start in a

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? For Methods one should be able to learn what extension to use, but here default or such do not help. Is there a wayplot.default to learn which different versions of

Hi, Sorry to bother, but I checked around and did not succed creating a bundle from six existing packages (which are checkable, installable, etc. individually).

Hi there, May I ask the following question. Our Solaris installation of Xemacs and R: SunOS fluke 5.9 Generic_117171-02 sun4u sparc SUNW,Sun-Fire-480R one cannot start R inside xemacs: M-x R "symbol's function definition is void".

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
