Dear all, I have two files, both of similar formats. In column 1 are Latitude values (real numbers, e.g. -179.25), column 2 has Longitude values (also real numbers) and in one of the files, column 3 has Population Density values (integers); there is no column 3 in the other file. However, the main difference between these two files is that one has fewer rows than the other. So what I'm

If I use latex(summary(X)) where X is a data frame with four variables I get something like Rainfall Education Popden Nonwhite Min. :10.00 Min. : 9.00 Min. :1441 Min. : 0.80 1st Qu.:32.75 1st Qu.:10.40 1st Qu.:3104 1st Qu.: 4.95 Median :38.00 Median :11.05 Median :3567 Median :10.40 Mean :37.37 Mean :10.97 Mean :3866

Dear all, I have used 'read.table' to create a data frame of 720 columns and 360 rows (and assigned this to 'Jan'). The row and column names are numeric: > columnnames <- sprintf("%.2f", seq(from = -179.75, to = 179.75, length = 720)). > rnames <- sprintf("%.2f", seq(from = -89.75, to = 89.75, length = 360)) > colnames(Jan) <- columnnames

Dear all, I'm having trouble interpolating a number of gridded datasets that I have. I'm quite new to R so any help/advice that can be offered would be much appreciated! Firstly I'll describe my dataset. The data is a grid of the planet at 1 degree spatial resolution, with each grid cell containing a value describing a particular variable (e.g. population density) for coordinate

Dear R Users, I have a data frame of 360 rows by 720 columns (259200 values). For each value in this grid I am hoping to apply an equation to, to generate a new grid. One of the parts of the equation (called 'p') relies on reading from a separate reference table. This is Table 4 at: http://www.fao.org/docrep/s2022e/s2022e07.htm#3.1.3%20blaney%20criddle%20method (scroll down a little).

Dear R Users, I am using the reshape package to reformat gridded data into column format using the code shown below. However, when I display the resulting object, a single column is fomed (instead of three) and all the latitude values (which should be in either column one or two) are collected at the bottom. Also, the NA values aren't removed, despite this being requested in the code. Code:

Dear all, I am attempting to add row and column names to a series of tables (120 in total) which have 2 variable parts to their name. These tables are created as follows: # Create table indexes index <- expand.grid(year = sprintf("%04d", seq(1986, 1995)), month = sprintf("%02d", 1:12)) # Read in and assign file names to individual objects with variable name components

I know that there are two method to apply the Hosmer and Lemeshow?s. One of them is calculated based on the fixed and pre-determined cut-off points of the estimated probability of success. One of them is calculated based on the percentiles of estimated probabilities. In the previous post,i find that the Hosmer and Lemeshow?s test how to use in R. hosmerlem <- function (y, yhat, g = 10) {

When secondary cpus are initialized during an i386 pv-guest restore (due to save/restore or live migration), and the guest has a load that generates a fair number of interrupts (e.g., parallel kernel make), a stack overflow can occur because cpu_initialize_context() has a 2800 byte structure it declares on its stack. linux-i386 has 4K stacks, by default. Using 2800 bytes out of 4K by a single

Hi, For those of you that attended RubyConf 2007, what were your impressions? Any more thoughts on JRuby, Rubinius, IronRuby or Wuby? Regards, Dan

Hi all, the commands "btrfs filesystem show" and "btrfs device scan" look at the /dev directory (and it subdirectories) for every block devices. This is a slow process because floppy and cdrom are also checked. Moreover, as highlighted by Helmut, if udev is not used, the /dev directory is populated by high number of non-existant devices, which slow the process. My patch

Hi, a few months ago I posted a message about using LDAP to store rsync secrets in LDAP. I received a response about patching the rsync source code with a patch file. I am now finally getting around to doing this, and when I tried to use the patch command 'patch --verbose ./rsync-2.5.6/authenticate.c rsync-ldap.patch' , it gives me the following error: Hmm... Looks like a unified diff

Hello, I have 2 variables in my sample Data: Data$A and Data$B Variable Data$A can assume values: 1, 2, 3, and 4. Variable Data$B identifies my cases and can assume values: 1 and 2. I need to recode my variable Data$A into a new variable Data$new such that: People who are Data[Data$B %in% 1, ] are recoded like this: Value on Data$A Value on Data$new 1 +1 2

Dear R-help-list, I have a problem in which the explanatory variables are categorical, the response variable is a proportion, and experiment contains technical replicates (pseudoreplicates) as well as biological replicated.
