Hi all, One of my variables looks like this: .7_-.3_-.2_.9 And this is a character variable. I made this by combining four different number like .7, -.3, -.2, and .9 using paste function. Now, I want to go back to original format from this one combined character variable. For instance, I want to extract 3rd number, -.2, from this character. I know I can use substr function, but each position

Hi all, I'm trying to using heat.color function in my data visualization. So, when I set col = heat.color(5), five different colors are displayed from red to weak yellow. But, now I want to know the color's keys or the names of the displayed heat.color. For instance, I think one of the five displayed colors seems to be 'red'. But, I'm not sure whether it is, also I don't

Dear All, I try to invoke a second program (called "gencont") within a R script. However this second program needs some time to finish. After finishing the output should be read into R and used for further calculation. Under windows, it perfectly works: result<-shell("gencont < yn.txt",intern=TRUE,wait=TRUE) # R waits untill the program finishes (apporx 3 min) and

Hello, I have a dataset with 4 variables, each consisting of a vector, all with the same length. I start by interpolating the first three variables using the function "interp", and plot the interpolation successfully using "filled.contour". I then interpolate the first two variables and a fourth using "interp" again, but when I try to overlay the contour lines

Hi. Maybe this is a stupid question. If so, I apologize, but here goes. Suppose I have a function f1(x,...) that calls a function f2(y1,y2,...,yn) in the following way: if x satisfies a certain condition, then I want to call f2(x,y2,...,yn); otherwise I want to use the default value of y1, if there is one. I could do something like the following: v <- ifelse ( is.null(x), f2( , y2,...,

Hi all, Is there a simple function already implemented for getting the ISO weeks of a Date object? I couldn't find one, and so wrote my own function to do it, but would appreciate a pointer to the "default" way. If a function is not yet implemented, could the code below be of interest to submit to CRAN? Best Regards, Gustaf --------------------

So far the only thing that I can figure out to do is to break the data file into three different files. The first file contains the x-coordinate data: x1 x2

Dear Mongrel Users, It appears that Francis still isn''t satisfied with my attempts to apologize and he''s now asked me privately to retract my statements. So, just to be sure he finally gets it: I retract my statements that Francis and his friends are "shady" and "desperate for cash". He is in no way a shady guy, having dealt with this situation with the

Dear all, I wonder if there are some function or package in R which can do the iterative proportional fitting. In the exponential model f(y1,...yn)=exp(a'yi+b'(yi*yj)+.....+c'(y1*...*yn)+constance), instead of the canonical parameters, I use maginal probability instead of a and log odds ratio instead of b. and for the order higher than 3, I use the canonical way or even assume
