Hello, the admonition of Prof. Ripley to search the documentation to solve my problem helped, today I read a lot more on Tcl/Tk than before ;-) But now I'm stuck again. With the help of my script some functions are plotted on the display, then I ask if the user wants to save it as pdf. In windows I use winDialog and it works. But I can't succeed in Linux. In short:

Is possible to avoid the warning message (or changing its contents) in tkgetSaveFile when the file to save already

Hello, it wanted to know how I can extract of a dates frame the values peaks according to an interval that I establish. For example if dates are: 1 23 2 4 3 56 4 7 5 99 6 33 extract the date i wanted to divide into intervals of 2 an d to take alone the numbers 23, 56 and 99 of those 3 intervals. Thanks Ruben

Hi, i 'dont understand how to take a general formula, view this: x<-1:5 y<-c(0,1,1.7,2,2.1.4) dummy<-data.frame(x=x,y=y) formula<-"y~A*log(x)/log(2)" formu<-as.formula(formula) fm<-lm(formu,data=dummy) Error in eval(expr, envir, enclos) : Object "A" not found but A is the parameter of fitting, why is this?Thanks Ruben

Hi, don' t understand why the function fomula have this error, i enclose the parameter "a" with the function I() Thank Ruben x<-1:5 y<-c( 2 ,4 , 6 , 8 ,11) formu<-y~I(a*x) form<-formula(formu) dummy<-data.frame(x=x,y=y) fm<-lm(form,data=dummy) Error in unique(c("AsIs", oldClass(x))) : Object "a" not found

HI, sorry but i don't understand how to make a function with as.function() formula<-"2+3*x" formu<-as.symbol(formula) > formu 2+3*x formul<-as.function(alist(x=,formu)) curve(formul,1,5,col="blue") Error in xy.coords(x, y, xlabel, ylabel, log) : x and y lengths differ > typeof(formul) [1] "closure" and not plot the curve function, Why?
