...rGrp[k] + i, ] <- xT[[k]] } X # That's I wanna get. #### But as soon as n, k increase it takes too much time because of the loops. Then my question is how can I get such a design matrix X without too much loops ? Which function I should look at ? Thanks in advance for responding me, Gildas

...inted 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

Dear R users, I'm looking for tools to perform optimization subject to constraints, both linear and non-linear. I don't mind which algorithm may be used, my primary aim is to get something general and easy-to-use to study simples examples. Thanks for helping, Gildas

Dear R users, Given a user-defined cumulative distribution function F, I want to compute F^{-1}(x). How is that possible with R? Best Regards, -- Gildas Mazo PhD student MISTIS team at INRIA Grenoble, France [[alternative HTML version deleted]]

Hello All, Want very much to learn how to plot patient drug timelines. Trouble is I need to figure out how to do this today. So not much time for me to struggle with it. Hoping someone can just help me out a bit. Below are some sample data and code that produces what I think is the beginning of a very nice graph. Need to alter the code to: 1. Get the lines for the drugs to appear on the

Hi, I have a data set of points which are represented by 3 variables x,y,z where x is the position of the point on the x-absciss and y on the y-absciss. Each of my points has a value z, which I want to be displayed as follows: the more z is high, the more the color on the map is dark. How can I achieve this ?
