Hi all, >From a vector, I want to get the unique values and the counts of these unique values in the vector. For example, x<-c(2 ,1 ,2, 1, 4 ,2 ,1, 4 ,1 ,1) xu<-unique(x) xn<-numeric(length(xu)) for (i in 1:length(xu)) {xn[i]<-length(which(x==xu[i]))} There must be a very much simpler method of doing this. Can somebody direct me to the functions that I must read in order to do

Dear r-help, I need to draw xyplot() graphs with several regression lines: one line for the whole range of x (the variable on the horizontal axis) and two additional lines for subranges of x. Is it possible to make first regression line (panel.lmline(x,y,...);) to be drawn on the whole graph and regression lines of the subsets to be drawn only over their subsets? I have defined

Dear r-help, Please, be so kind, tell me what does mean the parameter of layout.show()? I use R 1.6.2... Windows NT 4.0 Unfortunately I cannot understand phrases from the help "n: number of figures to plot." what figures? "`layout.show(n)' plots (part of) the current layout, namely the outlines of the next `n' figures." what figures?

Dear r-help, I draw graphics with xyplot() function. Labels on the y axis are appearing as follows: "1.5, 1, 0.5, 0" I'd like to have them to be "1.5, 1.0, 0.5, 0.0", i.e. with fixed number of digits after the dot (one in this case). Is there any way to do this without implicit specifying labels? And some questions about font. Unfortunately I cannot

Hi I'm generating the following in a file and getting a syntax error: bryansAtHeaderLevel <- c(0,1,1,1,1,0,0,0,0,0,0,1,0,0,1,1,1,0,0,0,1,0,0,0,0,0,0,1,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,1,1,1,1,0,0,1,0,0,1,0,1,0,1,1,1,1,1,1,0,0,1,1,1,0,0,1,1,0,0,1,1,1,1,1,1,1,1,1,0,0,1,0,1,0,1,1,1,1,1,1,1,1,1,1,0,0,1,0,1,0,0,0,) finnsAtHeaderLevel <-

Dear r-help, Now I am drawing graphs with xyplot function. In order to place a legend under the plots I use the key argument in the xyplot function. One of the 'key' components is 'divide', which defines a number of points on the each line of the legend. The default is 3 points. I would like a single point, so I set divide = 1. Call to xyplot didn't produce

Dear r-help, I have troubles with 'substitute'. I have the data frame with vectors data$area.0, data$area.20, etc... Command substitute(data$area.lon,list(lon=20)) returns data$area.lon but is expected to return data$area.20 Where did I do mistakes? -- Best regards Wladimir Eremeev mailto:wl at eimb.ru

Dear r-help I draw plots with xyplot() function. Each plot contains also a line of regression. I want to write the trend value and its significance (obtained with lm()) below each panel. I use ltext() for this. But the text is cut, when it comes outside a panel. Moreover (obviously), it doesn't appear at all when its coordinates are outside a panel. Could you,

Dear colleagues, I have troubles while trying to display legend on the plot.

Dear r-help, I've got data of the following structure 1979 93.428747 0 1979 87.298608 20 1979 78.506340 40 ... 1979 45.567890 340 1980 60.815289 0 1980 49.630904 20 1980 24.981362 40 ... The first column is year and the last one is the longitude. I need a set of graphs showing the dependence of the middle value on the longitude, for each year, situated one blow the other.

Dear r-help, I have an array a1 with dimensions [1:660,1:65,1:25] I would like the first dimension to be the last one. That is I want and array [1:65,1:25,1:660] The only way to do this, I know, is tmp.a<-array(dim=dim(a1)[c(2,3,1)]) for(i in 1:dim(a1)[1]) tmp.a[,,i]<-a1[i,,] a1<-tmp.a rm(tmp.a) Is it possible to avoid 'for' loop here? Thank you! ---

Dear r-help community, Thank you for your previous answers! Now I have strange behaviour of the lattice library funcitons. They do not draw graphics in the file when called from the script. I created the script file, called, for example, "a.R", containing the following library(lattice); trellis.device(device="png", filename="a.png",

Dear r-help, Unfortunately I cannot find in the documentation what determines ranges of a 'box' in the box-and-whisker plot. It is said in "Simple R" (http://www.math.csi.cuny.edu/Statistics/R/simpleR) that they are 1st and 3rd Qus usually. I tried to add to boxplot lines with (quantile(x,probs=0.25)), but lines do not coincide with edges of boxes.

Dear colleagues, I have the following code. This code is to 'filter' the data set. It works on the data frame 'whole' with four numeric columns: a,b,d, and c. Every row in the data frame is considered as a point in 3-D space. Variables a,b, and d are the point's coordinates, and c is its value. This code looks at every point, builds a cube 'centered' at this

Dear r-help, Function sd calculates the standard deviation 'with (n-1) denominator'. Are there any alternatives with n denominator? Thank you very much. -- Best regards Wladimir Eremeev mailto:wl at eimb.ru

Dear r-help, I need to unite contents of two files with variables into one data frame, produce some derivative variables from them and store them in that data frame. Here is the set of commands (processing first file for now) data7902<-data.frame(year=NULL,lon=NULL,area=NULL,extent=NULL,area.std=NULL,extent.std=NULL, area.norm=NULL,extent.norm=NULL);

Dear r-help, I have a matrix, suppose, 10x10, and I need the matrix 5x5, having in each cell a mean value of the cells from the initial matrix. Please, point me to a function in R, which can help me doing that. Digging the documentation and mail archives didn't give me a result. Thank you. --- Best regards, Vladimir mailto:wl at eimb.ru
