Hi there, Is there any package which can calculate the overlapping area of two polygons or output the coordinates of the overlapping of two polygons? Thanks. Haiyong

Hi there, I want to integrate a function over an irregular polygon. Is there any function which can implement this easily? Otherwise, I am thinking of divide the polygon into very small rectangles and use "adapt" to approximate it. Do you have any suggestions to get the fine division? Any advice is appreciated. Haiyong

Hello, I just want to ask if there is any function that can convert decimal number to binary vector. Thanks a lot. Haiyong

Hello, I want to reduce the distance between my ticks and their labels. I managed to do it for the x-axis, but the y-axis puzzles me. Here's an example where there is no space between the x-asix ticks and labels. par(las=1) plot(runif(50), type="l",xaxt="n",yaxt="n",ylab="", bty="l") axis(2) axis(1,padj=-1.5) #However, axis(2,padj=-1.5)

Hi R-users, I'm running R under Unix and producing postscript output of graphs. Soemtimes, some tick axis labels disappear from my output. eg if I have a vector months <- c("J","F","M","A","M","J","J","A","S","O","N","D") Then the "M" and one or 2 other

Hi Folks, I'm advising someone who's a beginner with R, and therefore wants the simplest answer possible. The issue is to produce a plot using plot(x,y,...) where, on the X-axis, the tick-marks should be on the lines of: -- Range of X-axis: 0:1000 -- tick-marks labelled "0","200",...,"800","1000" -- unlabelled tick-marks every 50 from 0 to

Hi, I would like to use xyplot to create a figure. Unfortunately, I cannot find documentation in xyplot to specify alternating the x-axis tick labels with the x-axis tick marks. I can do this with the regular R plot function as follows. #A small version of my data looks like this data<-data.frame(matrix(ncol=3,nrow=12)) data[,1]<-rep(c(1,2,3),c(4,4,4)) data[,2]<-rep(c(1,2,3,4),3)

Hi, I wish to create a series of plots with the same x-axis range and the same placement of tick marks. In addition I want to force the tick marks to be at specific locations. For example, if I wish to have an x-axis which goes from 40 to 110, with tick marks at 40, 50, 60, ... , How can I accomplish that? The various parameters I have tried changing just seem to be suggestions for

Hello, I think I found a bug: > windows(1,width = 10, height = 10, pointsize = 5,xpos = 0, ypos = 0 ) > hdata[1:3,1] <- c(1,10,15) > hdata[1:3,2] <- c(2,1,4) > plot(hdata[,1],hdata[,2],xaxt="n") > axis(1,at=c(2,10,14)) > minor.tick(nx=2, ny=1,tick.ratio=1) the minor tick marks appear between the tick marks which would have been drawn without the option

I'm trying to find a way to force all the x-axis tick labels to plot, regardless whether or not they overlap or look pretty. V is a factor with, say, 4 levels. A call to plot(V) gives a histogram-like plot, one bar for each level in V. The problem is that all the label names may not be plotted because some of the names are lengthy and would tend to overlap if plotted. I don't care

Is there a way to show also the intermediate tick marks without the values? Example: plot(cars) What would one do to show the tick marks in, say, gray color at the increment of 1 without showing the actual values in-between the default x values: 5, 10, 15, 20, 25? platform i386-pc-mingw32 arch i386 os mingw32 system i386, mingw32 status major 2 minor 2.1 year 2005 month

While writing a function that includes placing grid lines at the same position as the axis ticks, I found that the axis* functions don't return anything. Thus I have had to copy the appropriate function, removing the call to axis() and adding a line to return the tick positions. Is there a more elegant way to determine the tick positions on an axis? Thanks. Jim (normally bitwrit at

Hi, I'm stuck on creating a plot with x tick labels for every Nth tick mark - how is that done? I don't see a simple solution to this in help(plot) or help(par) and what I've tried is not working, eg, the following does not work, although it seems intuitive to me that it should work: x <- seq(-100,1000,25) y <- x * x % find all the x values that are multiples of 100 tmp <-

I am trying to generate a plot whose x-axis values are the following: data_out[,1] [1] 1979 1958 1937 1916 1895 1874 1853 1832 1811 1790 1769 1748 1727 1706 1685 1664 1643 1622 1601 1580 1559 [22] 1538 1517 1496 1475 1454 1433 1412 1391 1370 1349 1328 1307 1286 1265 1244 1223 1202 1181 1160 1139 1118 [43] 1097 1076 1055 1034 1013 992 971 950 929 908 887 866 845 824 803 782 761

Dear R-help list, I have a problem with the tick marks of a Kaplan-Meier survival plot. Here is a sample: follow.up<-c(10,20,30,40,50,60,70,80,90,100) #months dead<-c(1,1,1,0,1,1,0,0,0,0) KM <-survfit(Surv(follow.up, dead)) plot(KM) The result is a nice plot. However, our research group thinks it may be a better idea to place the ticks to the years on the time scale, i.e. 0, 12, 24, 36

For example, this works: x = seq(-100, 1000, 25) y = x * x plot(x,y, xaxt="n") axis(1,x,FALSE,tcl=-0.3) axis(1,x[x %% 100 ==0]) It creates two axis objects and the values of the x-axis are the labels. The following scenario is more difficult, because it uses 'image' to plot a grid of values: a = matrix(rnorm(100),ncol=10) image(1:ncol(a), 1:nrow(a), a, xaxt="n",

Full_Name: Gavin Simpson Version: 2.1.0-patched (1-Jun-2005) OS: Linux (Fedora Core 3) Submission from: (NULL) (128.40.32.76) axis.Date() insists on labelling tick marks. It could be made more flexible by allowing the user to specify if they want the ticks to be labelled, for example, to add un-labelled minor ticks for "months", added to a plot with "years" labelled.

Hi, I have a plot whole tick values along the axis have a certain range 0 - x . I need to normalize this range without changing my data files. for e.g., if my plot has tick values at 10,20,30,40,50... i have to make this 2,4,6, etc. but without changing the plot data... I am hoping I can add something to the plot command that goes like tick values divided by a quantity. Any help is appreciated.

Dear R-list, I am having trouble getting the Plot function to set the tick marks the way I want, and I am not sure what I am doing wrong. Below is the code that I wrote, and I am not sure why it doesn't work. p is a vector of length 2198, containing numbers between 0 and 240. q is a vector of ones, the same length as p. I want the x-axis to have tick marks every 30 min and I want the

Hi, I would like to plot a histogram with the following codes, and I would like to make the tick intervals smaller. I tried to add "lab=c(1,1,12)", but nothing changes. par(mfrow=c(1,1),font=1, cex=0.8) hist (data1, seq(-0.01,0.3,0.01),freq = FALSE, main="Figure1.",xlab="return",lab=c(1,1,12)) lines(density(data1), col="blue") Could anyone give me sone
