Hello R For expierienced user, the following problem will be easy to solve: a<-c(0,1,0,1,0,2,3,4,3,2) b<-c(3,3,3,4,4,4,7,7,7,10) c<-data.frame(a,b) Data Frame c contains tow colums. I would like to sum up all values in a as long as b stays the same: sum(a[which(b==1)]) does this, but i have to manually put in b then i tryied st like this, but i canno't save it properly for (i

Hi there I have an interesting problem: My csv file is of array dimensions [12,50], but it was saved the wrong way: there should be only 11 colums. What happens now if I read it into R is that the whole data set is shifted ( in the first row, the last column contains already the first value of the supposed second row and so on...) how can I tell R to switch after 11 read values to the next row,

Hello R, According to: g <- expand.grid(x = 1:10, y = 5:15, gr = 1:2) g$z <- log((g$x^g$g + g$y^2) * g$gr) wireframe(z ~ x * y, data = g, groups = gr, scales = list(arrows = FALSE), drape = TRUE, colorkey = TRUE, screen = list(z = 30, x = -60)) i have two wireframes in one plot. How could i change the color of the top - one to transparent (or only the grid).

...- and what I'm actually looking for is making just the UPPER (toplayer) transparent.

dear r-list I have a zoo object with 2 objects and time: looks like: 2005-12-31 12:00:00 NA NaN 2005-12-31 13:00:00 NA NaN 2005-12-31 14:00:00 NA NaN 2005-12-31 15:00:00 NA NaN 2005-12-31 16:00:00 NA NaN 2005-12-31 18:00:00 NA NaN 2005-12-31 19:00:00 NA NaN 2005-12-31 20:00:00 NA NaN 2005-12-31 21:00:00 NA

Dear all I try to print 9 plots on a page, arranged as the code shows below. nf <- layout(matrix(c(1,0,2,0,0,3,0,4,0,5,0,6,0,0,0,0,7,0,8,9), 10,2)) layout.show(nf) but when I try to plot, an error message Fehler in plot.new() : Grafikr?nder zu gro? appears to verify p.e. with plot(runif(10:1)) i tried with plot(runif(10:1), ann=F) to produce more space, but neither. The second

hej there I want to invert the yaxis as follows: x<-rnorm(1:50) plot(x^2, type="h", ylim=c(0,10)) plot(x^2, type="h", ylim=c(10,0)) then doing the following it won't work - kind of strange isn't it? x.zoo<-zoo(x^2) plot(x.zoo, type="h", ylim=c(10,0)) plot(x.zoo, type="h", ylim=c(0,10)) how can I invert the axis with zoo objects?

Dear R Plots without par arguments do start not at zero (means, the box around is somwhere outside the specified plotrange). How to start really from zero, pe. basline y=0? every standart par works like this: x<-seq(1,10,0.1) y<-sin(x) plot(sin(x)) Thanks for help Marc -- Ist Ihr Browser Vista-kompatibel?

hello could anyone tell my, why I do not suceed with mfrow? par(mfrow=c(4,4)) for (i in 5:17){ levelplot(maxwater[,i]~maxwater$V1*maxwater$V2, col.regions=whiteblue(5), xlab="", cuts=4) } Thanks Marc --

Hello R-classicist won't like the following question due to there's no minimal reproducible example and the question was posted already. Anyway I'm not able understand this rather complicated version of "add points to wireframe". what I have is matrix 3x2000 with a dem<-(x,y,z, coordinates) (not provided). with follwing code I want to produce the wireframe and add some

Hello does anyone know how to save in a variable with a loop part. Im reading several csv files with read.table and would like to save with a loop: for (i in 0:9){ } should give read0, read1, read2, read3, read4, read5, read6, read7, read8, read9 st. like read(i)<-read.table("myfile.csv".....) I tried with paste("read", i, sep"") or to save as a vector with

I may be posting to the wrong list here, and in that case I apologize in advance, but is there a way to configure the standard Centos 5 syslog daemon to use more local facilities than local0 to local7?
