Hello R users, For the last few days I am struggling with the following task: my data.frame: A1 A2 A3 B1 B2 B3 58.81 53.292 54.501 13.013 17.39 19.407 56.02 56.251 54.033 20.099 13.15 10.411 55.376 53.099 57.625 13.396 21.031 13.22 58.584 53.194 54.218 13.038 16.854 19.289 55.7 55.921 53.847 19.942 13.153 9.828 55.093 52.934

Dear R users, I came up to a problem dealing with percentiles in R. >From my previous questions: I do have a big data.frame, with lots of columns and rows. The following command enables me to calculate means for all data frame. dat1$newID<-rep(1:(nrow(dat1)/12),each=12) #if nrow(dat1)/12 is integer dat2<-with(dat1,aggregate(cbind(dat1[,1:71]),by=list(newID),mean)) What I need is to

Hello. I have data of potatoes production in EU during 1998-2009 from EuroStat where the first column consists of the names of EU countries, the following columns consists of appropriate data in each year. Let's say, I investigate Lithuania. For example, I have a row containing potatoes production in 1998, 1999, ..., 2009 in Lithuania. I can easily find the maximum value in this row but...

Odd question here but if I have asterisk running on PC (and mplayer installed). and a video phone calls up the asterisk PC can that video image be played on mplayer? If so how do I do that? How can asterisk pipe the video into mplayer so as to display the video image on screen? Thanks, Jerry

Hi, I am trying to learn some basic statistics stuff but I cannot find any elementary statistics exercises using R language. Using RKward would be even better... I need that in analysing sociological data, obtained through questionnairres - findind corelations between variables, relations between different types of data, etc. Could anyone recommend simple tutorials/exercises, available on www

Hi, does anyone know how to plot 3D parametric surface,e.g ellipsoid: x=a*cos(s)*cos(t), y=b*sin(s)*cos(t), z=sin(t); s in [0,2*pi], t in [-pi,pi]. Vytautas Maniusis, Vilnius University, Lithuania

Hey there all, Is there some way to tell rails or sql server to ignore the time in a datetime field when doing a comparison? For example, if I do something like select * from users where registration_date = ?, @date where @date might equal some user input like ''03/14/2006'' The result is nothing returned, because in my tables the datetime field looks like this: 3/14/2006

Estimados Soy un nuevo usario de R, y estoy usando como base de datos el European Social Survey, que tiene datos de 40,000 individuos, y alrededor de 23 países europeos. Lo que he seleccionado es la útima ola, el round 7, para el año 2014. He leido los datos, desde SPSS y aquí tienen la base de datos y que tipo de objetos se han generado, y tambíen la distribución por pais de la muestra. No he

Dear all, I would like to employ a European map in a presentation. My idea was to use: library(mapdata) map("worldHires", c("Austria", "Switzerland", "Germany")) where I include all countries from my analysis as a vector of character strings like in the example above. Unfortunately, I was unable to specify the Baltic States (Latvia, Lithuania, Estonia) or

Dear R users, I use: mapImageData<- get_map(source="google", c(lon=21, lat=57), zoom=6, maptype="terrain") to get ggmapTemp.png file in the directory. The problem is - some city and park names overlay with my data points I want to plot on this map. Is there a way to get the map without city, country and park names? I get this using maptype="satellite", but I

Hi, all. I'm using void LoopBase::getExitBlocks (SmallVectorImpl< BlockT * > &ExitBlocks) const to get all exit blocks for a loop. The problem I find with this API is that it returns repetitive basic blocks in certain situations. Should repetitive basic blocks be removed? I have an example to show the problem. Following is the source code and the CFG is enclosed. int main() { int
