Hello, I'm new to R, and I'm trying to set the number of tickmarks for a plot using xaxp, but R seems to ignore this setting completely. Maybe you've an idea what I'm doing wrong. I'm using R 1.4.1, and here's hat I'm doing: > d[,'seq'] [1] 28913 16323 13922 6237 4257 3881 4100 3781 2694 2064 1769 1550 [13] 1539 480 >

Hello, This is perhaps more of a regression question than R, but I am learning both, so would appreciate your wisdom here. I have some data which reflects power load for an electrical generating system, with some temporal features. The data fields look like this: D,MON,DAY,YR,HR,WDAY,DRYBULB,WETBULB,LOAD 4455 5 13 92 13 4 70 63 1617 4456 3 9 92 13 2 73

hi chaps: a simple suggestion: R tells me who the contributors() are, but this should also tell me where I should mail suggestions to. Is it this mailing list? a repository of suggestions? an individual? this came up because i wanted to suggest two small enhancements: the first is for the summary() method for plain data frames. it would seem to me that the number of "NA"s

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 there, I guess this must be a standard issue, but I'm starting to go crazy with it. I simply want a plot with the x axis being logarithmic, having labels 1, 10, 100..., and ten unlabelled ticks between each of them - just as they introduce logarithmic axis at school. I've played around a bit with log="x", xlog=T (where exactly is the difference here?), xaxp, and xaxt

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?

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, 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

Hey list, Does anybody knows a command to centre the tick mark labels exactly between the tick points (right shift)? And then to exclude the last tick label on the right? I know one can shift them using the 'hadj' option in par. But I am wondering if there is a more convenient command! Thanks a lot!! Stefan [[alternative HTML version deleted]]

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

I have a graph plotted in r.The x axis tickmarks are at 0,5,10. I need a graph with resolution of tickmarks at 0.1 interval.When i place tickmarks of 0.1 intervals using the following command axis(1, at=seq(0,5,0.1), cex.axis=0.7, las=2) I only get the tickmarks of 0.1 interval that are very closed placed in the graph.I need to increase the spacing between each tickmark. Please anyone help out

Dear R experts--- after many years, I am planning to give in and write my first R package. I want to combine my collection of collected useful utility routines. as my guide, I am planning to use Friedrich Leisch's "Creating R Packages: A Tutorial" from Sep 2009. Is there a newer or better tutorial? this one is 4 years old. I also plan on one change---given that the

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 R experts--- I am experimenting with multicore processing, so far with pretty disappointing results. Here is my simple example: A <- 100000 randvalues <- abs(rnorm(A)) minfn <- function( x, i ) { log(abs(x))+x^3+i/A+randvalues[i] } ?## an arbitrary function ARGV <- commandArgs(trailingOnly=TRUE) if (ARGV[1] == "do-onecore") { ?library(foreach) ?discard <-

I am about to become a new user of R, so apologies for a total beginner question. I need to graph some time-series. I would like to name the X-Axis with another series, say T. For example, the T series may have observations like "2003-12", which I would like to be the label. can this be easily done? as a new user: it would be nice if the FAQ listed the add-on packages in

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.

Dear R wizards: is there a clean way to assign to elements in a list? what I would like to do, in pseudo R+perl notation is f <- function(a,b) list(a+b,a-b) (c,d) <- f(1,2) and have c be assigned 1+2 and d be assigned 1-2. right now, I use the clunky x <- f(1,2) c <- x[[1]] d <- x[[2]] rm(x) which seems awful. is there a nicer syntax? regards, /iaw ---- Ivo Welch

Dear R Users, I have the following situations to plot. x-values (times) : range from 0 to 104 (in weeks) y-values (hazards) : range from 0 to 0.5 Now I want to make a plot of time versus hazards such that in the time axis (i.e x-axis) the values 0-24 occupies half of the axis and the values 25-104 ocupies the rest of the axis. In other words I want to emphasize on first 24

The treatment of dates seems to be a little inconsistent in R 2.11.1 (2010-05-31): [1] The choice of origins? > as.integer(as.Date("1970-01-01")) works and assumes as origin 1970-01-01. However, > as.Date(1) does not work. It requires an origin (as.Date(1, origin="1970-01-01")). If we set a default origin in the former, it should probably work when the input

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);
