similar to: Getting tick positions

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

Hi, A few times I tried to control the number and position of tick marks in plots with the yasp or xasp parameters. For example, a y axis was drawn by default with tick marks at 0, 20, 40, 80 and 100. I tried to get tick marks every 10 by adding yasp=(0, 100, 10) but this had no effect at all. I know I can draw the axis and tick marks manually, but often this simple option would suffice

Is there a function that does the same as pretty but on a log-scale? Suppose you have x <- exp( runif( 100, 0, 6 ) ) (which will between 1 and 403), then I would like to have a result like: log.pretty( x ) [1] 1 5 10 50 100 500 Bendix C. ---------------------- Bendix Carstensen Senior Statistician Steno Diabetes Center Niels Steensens Vej 2 DK-2820 Gentofte Denmark tel: +45 44 43 87 38

Is there an easy way to return the values of the axis tick marks resulting from plot.default? For example, plot(1:1000) would return 0, 200, 400, 600, 800, 1000 from the x axis. Thanks, Max --------------------------------- [[alternative HTML version deleted]]

I am displaying several series in one plot, and would like to make them distinct without having to employ a legend. I managed to color tickmarks, but have been unsuccessful with either one of a) making tickmarks thicker (without increasing the axis at the same time). From reading ?axis: lty, lwd: line type, width for the axis line and the tick marks. in would appear that I cannot

Dear All, I've done some searching, but to no avail -- I'm plotting x-y data via the "plot" command, and the "log=x" command. The graphed x values are in scientific notation (1e-02 1e-01 1e+00 etc). Might you have some idea on how I can get the plot to uses the x values (0.01 0.10 1.0 10.0 etc) instead? A related Q - where might a good place to search for such

I am having a problem with a gantt chart since moving to R2.4.0. from 2.3.1 I made some adaptations to the code from http://addictedtor.free.fr/graphiques/RGraphGallery.php?graph=74 and successful produced a simple gantt chart. However when I upgraded to 2.4.0 it no longer works as desired. See http://ca.geocities.com/jrkrideau/R/gantproblem.pdf for the two charts. The charts were produced

hello, all my attempts to get a plot with tick marks on both sides of axis failed - can someone please help me with this? thanks, kay ----- ------------------------ Kay Cichini Postgraduate student Institute of Botany Univ. of Innsbruck ------------------------ -- View this message in context: http://r.789695.n4.nabble.com/tick-marks-on-both-sides-of-axis-tp2336668p2336668.html Sent from the

Running R 1.2.3, Windows 98 I checked the archives, and I couldn't find anything pertaining to this: How do I control format (scientific notation versus decimal, e.g.) on tick labels?

I using lattice to make some plots and I want to make the y-axis on some of these plots use a log scale. In the following plot: x <- 1:10 y <- 2^x xyplot(log10(y) ~ x) I get tick marks on the y-axis at 0.5, 1.0, 1.5, 2.0, 2.5, and 3.0. I would rather have just 3 tick marks at 1.0, 2.0, and 3.0 but labeled 10, 100, and 1000. I know this can be done using the "at" and

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

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

Colleagues R 2.8.0; OS X, Vista, Ubuntu Linux In some instances, when I create a graphic using plot(XVAR, YVAR), it would be valuable to know the values that R will display on the y-axis (e.g., if the range of data is 0-70, it might display 0, 10, 30, 50, 70). Is there a simple means to access these values? Also, in some instances, additional ticks appear between the displayed values

Hi R list, I like the default ticks that are set up using grid.xaxis() or grid.yaxis() with no arguments. Finding good values for the 'at' argument is usually not a trivial task; the default behavior of these functions seems to work well. The problem with this strategy is that I cannot figure out how to "recover" the positions of these ticks when you do NOT specify the

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 know how do R calculates the number of intervals between tick-marks in the y axis in a plot. I'm making a three y-axes plot and this information would help me a lot. Thanks in advance. Antonio Olinto ---------------------------------------------------------------- Webmail - iBCMG Internet http://www.ibcmg.com.br

Hello, I am a new user. I would like to know if it is possible with R to fix the position of ticks. for example for my plot I obtained automatically the positions 200,400,600,800 and 1000 on x axis and so a scale of 200 But I would like to obtain 100,200,300,400,500,600,700,800,900,100 so a scale of 100. Which fonction can help me to do so? thank you meriema

R-Helpers; This seems simple to set graphic parameter, but I tried plot a graph with 10 intervals in x axis with par(xaxp = c(0, 150, 10) but to no avail: par(xaxp =c (0, 150, 10)) plot(age, y18, type="n", ylab="Height (m)", xlab=" age (Yrs)", font = 2) lines(age, y6, lty = 4, lwd = 2) lnes(age, y10, lty = 1, lwd =2) lines(age, y14, lty = 2, lwd =2)

I think this is a bug; at least this behavior is not documented in plot or plot.default. plot.default resets xaxp, and leaves xaxp reset when it exits: par(xaxp=c(0,1,4)) print(par("xaxp")) plot(c(0,1),c(0.2,0.3)) print(par("xaxp")) R.
