Possible error in ?axTicks
Hi all, Before posting to r-bugs, I thought that I would just verify this one first. It looks like the help for axTicks() needs to be corrected. It presently says: 'axTicks()' can be regarded as an R implementation of the C function 'CreateAtVector()' in '..../src/main/graphics.c' which is called by 'axis(side,*)' when no argument 'at' is specified. However, CreateAtVect...

axTicks.Rd documentation bug
?axTicks says: usr: numeric vector of length four, defaulting to ?par("usr")? giving horizontal (?x?) and vertical (?y?) user coordinate limits. but this is not how the function is implemented -- in fact 'usr' should be a vector of length two corresponding to th...

pretty for a log-axis
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

axTicks and window resizing

Plot label axis with expression

How to add a top X-axis with a different logarithmic scale?
Hi, I am trying to put on one plot two different logarithmic scales, using the bottom and top X-axes. Below there is an example of what I am trying to achieve, using axTicks() -- and fails. I already spent few hours on that, and cannot figure out from ?par and ?axTicks what I am doing wrong. Example follows: ############################################################ #### Data x <- c(1.1*1:4, 25*1:5) / 50e+03 y <- c(0.15*1:4, 0.6 + 0.05*1:5) #### Con...

vectorized plotmath expressions via substitute()
hi all - i've seen versions of this question before, but none seem to get directly at my solving my (probably very simple) issue: i simply want to annotate the tick marks on an axis with (superscripted) 10^x notation, and tried this: axis(1, at = axTicks(1), as.expression(substitute(10^foo, list(foo = axTicks(1)))) thinking the as.expression/substitute would create the appropriate expression vector from the expansion of the foo vector. i'm continually stuck in the error process, however, with axis() where R complains that i've only provid...

Formatting of numbers on y axis
Hello all. I have the following: plot(salaries$yearID, salaries$salary, type='n', xaxt='n', xlab='', yaxt='n', ylab='') axis(1, at=unique(salaries$yearID), labels=unique(salaries$yearID), lwd=.25, tck=-0.05) axis(2, axTicks(2), format(axTicks(2), scientific = F)) Which nicely creates the Y axis with the raw numbers, which are in the range of .5 - 7 million. However, it displays them as "1000000", and so on- I'd like it to show just whole numbers 1, 2, 3, through 7, so I can label the Y axis "in m...

Labels on axes with log scales with lattice
...and. xyplot(log10(y) ~ x, scales=list(y=list(at=c(1, 2, 3), labels=c(10, 100, 1000)))) My problem is that I am making multiple plots and cannot set the labels on each plot individually. I need to automate the computation of the "at" and "labels" parameters. I think the "axTicks" command can compute the information I need to set "at" and "labels" correctly, but I am having trouble determining how to set its parameters to make it compute the information I need. Perhaps "pretty" might work to, but "axTicks" seems better designed...

Month name in English, not R running language
...the language of R, but I search rather a way to change it for just the next command (also I run R in MacOS !). The solution will be to make myself the axis... except if someone has the trick to do it more easily. To generate the axis myself, it is not so simply to get one tick by month. I try axTicks(1) but it gives 5 ticks rather than 4 and > as.Date(axTicks(1), "1970-01-01") [1] "2000-04-13" "2000-05-03" "2000-05-23" "2000-06-12" "2000-07-02" Is not what I expected. Plot with date object seems to use a special way to generate...

R-help - Problem in drawing braplot with a huge value of data
Hello R-experts, I am facing a strange problem while creating a barplot. I have serise of data of which the first on is around 162589 while the remaining data are around 0-150. so when I am ploting the barplot with all the data I am getting a single line -> test1.jpg. But If I remove the 1st value i.e 162589 then I am getting a normal barplot -> test2.jpg Can some one help me regarding

returning plot tick marks
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]]
