similar to: How to define specific location of tick marks in plot()

hi, i am using par(mrow=c(6,6)) function to get 6x6 plots on one screen. the problem that i am having is that the axis tick labels are far away from the ticks and going into previous plots (see attached figure). i need to know how can i reduce the distance between the ticks and their values (y axis values).the part of the code that i am using (after reading in the data) to create the top row is:

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

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

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 all, I'm trying to log chart but with natural looking tick marks. My specifications are very specific -- it must indicate the lowest number's tick as well as the maximum. I've attached sample code and data for a particular case (and there are a few more like this) where the bottom tickmarks on the chart are not set to where I want them to be and yet they fit in the ylim range.

Dear R-helpers, I am having difficulty making R plot only integer labels on the x-axis of a simple graph. I want to plot the median values of a score on each of three occasions. Non-integer occasions are impossible. But, R keeps labelling the x-axis with half-occasions, despite my attempts to stop this using the "xaxs" and "xaxp" parameters of 'plot'. p1=c(1,2,3);

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)

Hello, Is there a way to define the width of the axis tick marks on traditionnal plots? I did not find anything specific on this topic in the help and par(lwd=...) does not affect the tick marks. I guess that using axes=FALSE and recreating the axis with the axis() command could do the trick but I wonder if there is no easier way. Thanks in advance Sebastien

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

I have been experimenting with various approaches to plotting (irregular) time-series with reasonable success. One thing I have been able to do is change the number of tick marks on the axis. Consider the following simple example: > x <- as.data.frame(matrix(ncol=2,nrow=500)) > names(x) <- c("dates","values") > x$dates <- as.POSIXct(Sys.time()+1:500*86400)

Dear R People: I am drawing graphs for a College Algebra class. I would like to have the x and y axes, along with the lines that I am plotting. So I leave off the axes, and use xlim and ylim. Then I add my abline(v=0). However, I would like to have tick marks on the abline. How would I do that, please? Thanks in advance! Sincerely, Erin M. Hodgess, Ph.D. Associate Professor Department of

Dear R Users, I am trying to get plot.zoo to place monthy tickmarks/labels for a time series which spans daily data going back a bit over a year. Right now, I am getting only one tick mark on the x-axis for the beginning of 2008. How can I force plot.zoo to place more regular x-axis tick marks on a monthly basis ? Thanks in advance, Tolga Generally, this communication is for informational

Using the standard plotting routine in R, i.e. no special packages, is there a way to add in minor tics to the axes? Also, is there a way to make sure the major axes labels are at the origin? When I'm looking at a plot, the major axes labels are present, but it looks like they start a bit away from the origin on the plot. Thanks again for any info and feedback.

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

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

Dear Daniel and Jorge, Thank you very much and it does help. If I have a string "ABCD", how can I access the second element of the string "B"?

hi all- i am creating a boxplot and would like to shift the x-axis tick marks (named 1:23) so that the ticks are in between the boxes and not centered in the middle of the boxes. i have searched the help files and google and have not found what i am looking for. does anyone know how to do this? thanks! s.heck University of Colorado, Boulder

R colleagues, I am stumped. I would like the inter-tick distances to be the same on the x and y axes but cannot determine how to do so when the lower half of the y axis is not printed. Thanks for any and all suggestions. (btw, setting par(pty="s") does not solve my problem) Niels Waller M<-matrix(c(2,1, -1,3),2,2,byrow=TRUE)

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.

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)
