Dear R helpers I am working on the Bi-variate Normal distribution probabilities. I need to double integrate the following function (actually simplified form of bivariate normal distribution) f(x, y) = exp [ - 0.549451 * (x^2 + y^2 - 0.6 * x * y) ] where 2.696 < x < 3.54 and -1.51 < y < 1.98 I need to solve something like INTEGRATE (2.696 to 3.54) dx INTEGRATE [(-1.51 to 1.98)]

Dear R helpers,   I have two queries.   (1) If the dataset contains some variables having all the entries = 0 and while analysing I want to delete those pericular columns, how do acheive this. i.e.   dataset1   sr_no    var1      var2       var3        var4        var5 1           5           0          3              1           0 2           3           0          2              9           0

Dear R helpers I have following dataset rate_number = matrix(c(5, 15, 60, 15, 5, 0, 20, 60, 20,0, 10, 20, 40, 20, 10), nrow = 5, ncol = 3) range_mat = matrix(c(6.25, 6.75, 7.25, 8.75, 9.25, 9.75, 8.5, 9, 9.5, 10.5, 11, 11.5, 4.25, 4.75, 5.25, 5.75, 6.25, 6.75), nrow = 6, ncol = 3) > rate_number        [,1]   [,2]   [,3] [1,]    5     0      10 [2,]   15   20      20 [3,]   60   60      40

Sorry, this is going to be a rather long post...Here's the situation; I have 4 IDE disks from an old snap server which fails to mount the raid array. We believe there is a controller error on the SNAP so we've put them in another box running CentOS 5 and can see the disks OK. hda thru hdd looks like this Disk /dev/hdd: 185.2 GB, 185283624960 bytes 255 heads, 63 sectors/track, 22526

This should be easy but it does not work I have 3 vectors*(activeT,inactT, activeR)*, the idea is that if the last value in inactT is higher than the last in activeT this value has to be append in active T and the last value in another vector call activeR has to be repeated. (at the bottom you can find the vectors) I have done this: activeT=round(as.numeric(activeT)) inactT=

Hi all, I''ll be at LISA starting tomorrow afternoon. I have a panel with other config-mgmt authors on Thursday and I''m running BoFs at night, but I''ll otherwise likely be trawling the hallways looking for conversation. Track me down if you''re there; I''ll do my best to wear a bike cap every day or something to simplify recognizing me. --

I have two models Program and PointOfContact and here is their relationship Program belongs_to PointOfContact PointOfContact has one Program There is a single form to input a program and it''s associated point of contact information.

Automated update system supplied with Fedora. Kinda like the RHN, but free and more up to date version-wise, but without the package checking done by Redhat. If you're running Fedora and it's installed, typing "yum update <package name>" will update a package to the latest version on your downloads site (it defaults to download.fedora.redhat.com), yum install <package

A conditioning factor for bwplot() is the stream name. There are 17 streams so each panel is comparatively small and the names in the panel header are truncated at both ends. I would like to wrap the names on two lines for each panel but do not see if this can be done when I look at the online docs (?bwplot) or the Lattice book. Is there a way to fit long strings as headers with multiple panels on

Hi Everybody I want to print a latex table containing math characters in the column heading These are the formulae I want to use as column headings. It prints OK from TeX $\sum_{i}\sum_{j}C_{P,i,j,y}\times\mathit{FC}_{i}$, $XU_{alt,y}$, $n$, $\bar{C}_{P,y}$ My plan was to create a character vector with these and later rbind the values to them. When I create the vector like:

Consider: > x <- matrix(1:6, 2,3) > rownames(x) <- c("ID1", "ID2") > colnames(x) <- c("Attr1", "Attr2", "Attr3") > x Attr1 Attr2 Attr3 ID1 1 3 5 ID2 2 4 6 > write.csv(x,file="x.csv") "","Attr1","Attr2","Attr3" "ID1",1,3,5

Hi, in 'Writing R Extensions" of R v2.10.0, under Section 'Cross-references' (2009-09-07) it says: 1. "The markup \link{foo} (usually in the combination \code{\link{foo}}) produces a hyperlink to the help for foo. Here foo is a topic, that is the argument of \alias markup in another Rd file (possibly in another package)." 2. "You can specify a link to a different
