Dear list, I am trying to write a function that will make a matrix of each row of a data frame (4 columns), calculate a fisher.test on each resulting matrix and assign a vector of the p-values. I have gotten through making the matrices, but cannot calculate the fisher.test. fm<-function(x) {dfrow<-nrow(x) mm <- vector("list", dfrow) for(i in 1:dfrow) mm[[i]] <-

Hello R users, I have windows XP running Rv2.6.0 and a Solaris OS 10 x86-64 running Rv2.4.0. I transferred several large .rda files from windows to linux because of memory issues. I saved as .rda files on windows. In linux, the files load and have the proper dimensions, but will not index. I get the following error: "negative length vectors are not allowed". However, I can load

Dear List, I would be pleased if someone can help me with the following issue: I'm about to plot two time series in one plot via ts.plot which looks like: ts.plot(series1, series2, main=main, xlab=xlab, ylab=ylab, col=c("green", "red", "blue"), lwd=2) The problem is, that R automatically sets the x axes labels in 5-year-intervalls. Every

Dear all, I wonder what's special about spinograms {vcd} that prevents me from using it the way I do with other plots. I do: > spine(f.speaker.identity ~ x.log.lengthening, > data=ms,breaks=45,gp=gpar(fill=c("red","green")),xlab="length difference > (log ms)",ylab="speaker") > curve(0*x,add=T) Error in plot.xy(xy.coords(x, y), type =

Hi All, After a lengthy battle just to get the package installed, I am not able to actually use Rgraphviz to generate any plots. I tried just using the sample code in the documentation (http://www2.warwick.ac.uk/fac/sci/moac/people/students/peter_cock/r/rgraphviz/) and I get the following: *> > library(Rgraphviz) > test.matrix<-matrix(rep(c(0,1,0,0), 9), ncol=6, nrow=6) >

Hi, I noticed the following problem with xy.coords() in R 2.2.1-patched (version info at the foot of this email) and R 2.3.0 unstable (subversion no: r37123): > xy.coords(x = matrix(1:20, ncol = 2)) Error in xy.coords(x = matrix(1:20, ncol = 2)) : argument "y" is missing, with no default > xy.coords(x = matrix(1:20, ncol = 2), y = NULL) $x [1] 1 2 3 4 5 6 7 8 9

Hello, I want to add text annotation about correlation on "pairs" plots. I found that I could pass a function to the "panel" argument of pairs : panel.annot <- function(x, y, ...) { points(x, y, ...) c <- cor.test(x, y) legend("topleft", legend=substitute(rho == r, list(r=sprintf("%.2f", c$estimate))), bty="n") } And then :

In ?xy.coords it says: If 'y' is missing and 'x' is a formula: of the form 'yvar ~ xvar'. 'xvar' and 'yvar' are used as x and y variables. list: containing components 'x' and 'y', these are used to define plotting coordinates. time series: the x values are taken to be 'time(x)' and the y

Hi, people. xy.coords() does not behave like its documentation says, when given some matrices. ?xy.coords says: If 'y' is 'NULL' and 'x' is a [...] formula [...] list [...] time series [...] matrix with two columns [...] In any other case, the 'x' argument is coerced to a vector and returned as *y* component [...] Now, consider this short

Dear Rhelp, I would like to get alternate tick labels for the xyplot: library(lattice) library(grid) xy <-xyplot(decrease ~ treatment, OrchardSprays, ??? main= "Some plot", ??????? groups = rowpos, type = "a", ??? ??????????? page???? = function(n){ ???????????????????????? grid.text(LETTERS[j], ???????????????????????? y = 0.95, ???????????????????????? x = 0.15,

Dear all, I need to run a interactive procedure where the user will need click on the screen (over a XY plot) and I need to record the XY coordinate which the user clicked. Roughly I wrote a short code below. You see that I suppose that the user will choose four coordinates inside the region of intersection between three segmentes. On each click, I would like to record the position clicked in a

Hi there, When I run the code below I get the error Error in xy.coords(x, NULL, log = log) :(list) object cannot be coerced to type 'double' Any tips how I can resolve this? > > library("waveslim") > > vols=read.csv(file="C:/Users/ocuk/My Documents/Abs Vol.csv", header=TRUE, > sep=",") > x<-c(vols[,1]) > #x > #data(ibm) >

Is there a way to teach xy.coords, when given log="xy", or just "x" or "y" separately, to do a decimal log10 instead of the natural log? Cheers, Alexy

library (ellipse) shape1 = c (1, 0, 0,1) dim(shape1) = c(2,2) ellipse (center = c(0,0), shape = shape1, radius = 1) ============================= Error in plot.xy(xy.coords(x, y), type = type, col = col, lty = lty, ...) : plot.new has not been called yet It is really frustrating. Also what do the shape matrix, radius correspond to an ellipse function (x-x0)^2/a + (y-y0)^2/b = 1 ?

Thanks in advance for any help. I am attempting to add points to a plot using the allEffects command in the effects package. When I try to add the points I get the following error message: Error in plot.xy(xy.coords(x, y), type = type, ...) : plot.new has not been called yet Strangely, using the code I've pasted below this has worked for me in the past however figuring out what has

Dear list, As can be seen below, adding a NA to the y values in a call to isoreg results in a segfault. ir4 <- isoreg(1:10, y4 <- c(5, 9, 1:2, 5:8, NA, 8)) Adding missing values to the x values, on the contrary, gives an error, but maybe the error message could be tailored to this particular situation. y <- c(5, 9, 1:2, 5:8, 3, 8) x <- c(1:9, NA) isoreg(x, y) ## error message:

Dear All, We aim to remove the spatial structure of our data using Moran Eigen Vectors and spdep package . Our data has 3694 samples and 13 variables. The computer stop working after almost 4 days of processing (we found it emitting a sharp sound and with all colors on the screen. No wories, it was restared without problem!). And we are left with nothing: no result file was produced since the
