Dear R experts, I have 2 matix: A& B. I am trying to index B against A - (1) find out B rows that fall between the col 1 and 2 of A& put them into a new vector SNP.I made code as below, but I cannot think of a right way to do it. Could anyone help me with the code? Thanks,Jiang---- A <- matrix(c(35838396,35838674,...

Just thought you'd like to know that SP1 for Windows XP breaks romaing profiles up to and including 2.2.5. This has been confirmed by MIT at the following link: http://web.mit.edu/swrt/winxp/ See the section "Software Compatiblity Test Matix/Testing SP1" We have found this to be the case as well.... I'm cross-posting this to samba-technical as well....we will work on some traces for you guys.... Some (maybe) helpful messages when logging on are: "The data area passed to a system call is too small" "The sys...

Dear R-users: I am runing R 1.6.2 with Windows XP. I try to calculate Pearson correlation and Spearman correlation of any pairwise columns of 8000 x 80 data matrix with missing values and randomize the matix 1000 times and calculate this two correlations again. The code bellow for Pearson is working fine but for Spearman got the error bellow for randomized data matrix and R console is stop working: cor (raw2[,i], raw2[,j], use="complete.obs") cor.test (raw2[,i], raw2[,j], method="s...

Hi, I am new to R, I am doing quantile normalization with a dat matix of 384X124 and I find that while computing the quantile normailzation it introduces 'NA' into some of the cells, can someone help me to overcome this problem ? This is the command that goes like upto g62 for 124 colomns >g1 <- normalize.quantiles(exprs(MSExpr[,1:2])) For a small s...

...e simply needs to compute -2.52830-(1.96*0.01085) and -2.52830+(1.96*0.01085). To get the estimate for "regional" one needs to compute intercept + typeregional, i.e. -2.52830 + 0.33788. To get the 95% CI is somewhat more difficult as one needs to use results from the variance-covariance matix, specifically the variance of intercept, the variance of "regional", and the covariance of (intercept,"regional") which involves: var = var(intercept) + var(regional) +2*(covar(intercept,regional)), and then get the SE of the variance SE=sqrt(var) 95% CI = intercept + regio...

Hi, I would like to know if there is a library that provides an API to support map scrolling, like the one available in google maps. This is, I would like to create a user interface where the user is able to see a small part of a large map. It can then move the view, thus observing another part of the map. Additionally, I would also like to provide a zoom mechanism. Thanks in advance. --

  Hello list, i have a very simple question about matrix assignment. i did like this. res<-1:30 dim(res)<-c(5,6) ind<-1:6 now i want to assign the value of this variable ind to first coloumn in matrix res. like res[,1]<-ind but this code is giving error , Actualy i have a for loop and value of ind variable is changing every time ,,total 6 times,,i want to assign every vlaue
