Hi all, I am having trouble assigning a value within a vector using a variable defined within a function. I suspect this has something to do with namespaces but I cannot figure it out. Please reply directly to me if you can help. ###begin code #simple vector test<-c(4,5,6) #simple function to get a value from a vector #works just like I would expect, has no problem indexing using the local

I can't seem to use the point-and-click identify() function properly. I'm running R 2.5.1 (I know, I need to get around to upgrading) under Win XP. The problem is, when I click on a point on the graph, I get an error, "no point within 0.25 inches." But in some areas, I can click where there is no visible point anywhere close, and an identify() label will pop up. The troublesome

Hello, This maybe a newbie question. I have a dataframe that looks like the sample at the bottom of the email. I have monthly precipitation data from several sites over several years. For each site, I need to extract years that have a complete series of 12 monthly precipitation values, while excluding that year for sites with incomplete data. I can't figure out how to do this gracefully

Hi R folks, I have a massive array (object name "points") in the following form [,1] [,2] [1,] 1369 22 [2,] 1370 22 [3,] 1368 23 [4,] 1369 23 [5,] 1370 23 [6,] 1371 23 (10080 rows truncated) These represent pixel coordinates of interest in a jpeg image. I need to find the distance from each point to all other points of interest. The only way I can see to do this

Hello, I am trying to use Sweave to write up a report, and I have used the plm package to do some panel models. I am trying to use xtable to make a nice table for my regression objects (returned by the plm command), but I am getting the error: Error in UseMethod("xtable") : no applicable method for "xtable" It seems like I would want to have xtable treat plm objects exactly

Hello, I have two time series objects, 1 is yearly (population) and the other is quarterly (bankruptcy statistics). I would like to produce a quarterly time series object that consists of bankruptcy/population. Is there a pre-built function to intelligently divide these time series: br.ts = ts(data=br.df[,-1], frequency = 4, start=c(2001,1), end=c(2008,2)) distPop.ts = ts(data=distPop.df[,-1],

If Compiz is running when the resume process switches back to X after having suspended, my X server locks.
