Hello! I'm trying to *save values* (*row and col*) in two matrices(1,m) or vectors. I have a loop, where a get these values: for(i in 144){ for(j in 73){ if(B4[i,j]==1){ # B4 is a matrix(73, 144) row <- B4[i-(i-1),j] col <- B4[i,j-(j-1)] } } } *How to save row and col?* Thank you! -- View this message in context:

I am puzzled at the use of regression. I have a categorical variable ClassePop33000 which factors a Population variable into 3 levels. I want to investigate whether that categorical variable has some relation with my dependent variable, so I go : lm(Cout.ton ~ ClassePop33000, data=ech2) Call: lm(formula = Cout.ton ~ ClassePop33000, data = ech2) Residuals: Min 1Q Median 3Q

Hi Using the ggplot2 package, I would like to obtain a plot that contains two time series that have data points on different dates. For instance, one data frame looks like: date1, value1 2010-01-05, 2921.74 2010-01-08, 2703.89 2010-01-14, 3594.21 2010-01-20, 3659.22 The other data frame looks like date2, value2 2010-01-01, 285.85 2010-01-02, 229.20 2010-01-05, 333.91 2010-01-06, 338.27

Hi all, I recently performed a series of compiler performance tests on FreeBSD 10.0-CURRENT, particularly comparing gcc 4.2.1 and gcc 4.7.1 against clang 3.1 and clang 3.2. The attached text file[1] contains more information about the tests, some semi-cooked performance data, and my conclusions. Any errors and omissions are also my fault, so if you notice them, please let me know. The

I apologise for writing again about the problem with using stepAIC + multinom, but I think the reason why I had it in the first place is perhaps there may be a bug in either stepAIC or multinom. Just to repeat the problem, I have 126 variables and 99 cases. I don't know if the large number of variables could be the problem. Of couse the reason for doing a stepwise method is to reduce this

Hi, I have a question about estimating IRT models by using nlme, not just rasch model, but also other models.

Hello, I''ve recently installed a hvm domU opensuse 11 guest and I cannot set the screen resolution higher then 640x480. This seems very strange to me, because I don''t have any problem to set higher resolution on a windows 7 domU, using the following parameters in the configuration file: stdvga=1 videoram=16 What could the problem be? Is some video driver missing? -- Flavio

Hello! I have a contour and I need *to rotate* it 180 degrees counterclockwise and 180 degrees around the x-axis. This is a code. I get all the values from the ncdf file: A = get.var.ncdf(nc, "air", start=c(1,1,1,1), count=c(144,73,1,1)) contour(A) Thank you! -- View this message in context: http://r.789695.n4.nabble.com/How-to-rotate-a-contour-tp3750710p3750710.html Sent from the R
