Hello, A stupid question: I have an array with two columns, the first "a" acting as my index in 0.25 steps, the second one "b" the column of interest. How can i sum up "b" only for a specified window in "a" (as the window command for time series) a=seq(0,10,0.25) b=runif(41) c=data.frame(a,b) Sum up c if 3<a<5.25 How to do that? thanks marc --

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,

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

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).

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?

Hello again With the poylgon function it's possible to plot shaded areas under a curve. But somehow it connects the start and the endpoint of a line and fills whats between them. I would actually like to set the boarders of the shading by two min and max curves, but I failed. i tried stl like: polygon(min, max, border=0), where min and max are my curves plotet by plot(max) lines(min)

Hello R freaks I have the following problem: I have several image plots, that need to have the same axis. i want to specify the range from 0 to a maximum value. The problem is, that the axis then only goes to the highest value of the respective plot. E.g: this is a modified example from the help file "image.plot" z values go until 25. My maximum in plot two is set to 30, so I want the

Hello R cracks The image() function requires strictly increasing x and y values and z as a matrix. Actually, I don't have equally spaced variables, but anyway want to plot an colored image() (with z-information). An example of my problem is here: a<-data.frame(rnorm(100), rnorm(100), runif(100)*100) How can I plot this data as an image (x=a[,1], y=a[,2] and z=a[,3])-> according to

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

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.

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

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 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
