similar to: ylim with only one value specified

I'm looking for an R mentor. I want to propose a change in management of plot options xlim and ylim. Did you ever want to change one coordinate in xlim or ylim? It happens to me all the time. x <- rnorm(100, m=5, s=1) y <- rnorm(100, m=6, s=1) plot(x,y) ## Oh, I want the "y axis" to show above x=0. plot(x,y, xlim=c(0, )) ##Output: Error in c(0, ) : argument 2 is empty

[This is an edited version of an email that I sent to Paul Murrell. He was in favour of the idea (although he noted the obstacles that: it could make par() longer; somebody has to implement it) and suggested I submit this as a wishlist item.] Do you think it would be worth adding options to plot commands to reverse axes? Here is a simple example: > x <- 1:12 > plot(x) Whereas if I

Hi list, I have a function which basically is a wrapper of pairs with some useful panel functions. However, I'm having trouble to pass the "xlim" and "ylim" into the function so the x and y axes are in the same scale and 45 degree lines are exactly diagonal. I've looked at some old posts, they didn't help much. I think this is b/c I have multiple panel

Today's R-devel has a problem in `example(medpolish)'. It appears that the `plot.medpolish' method is not available. Here is the output and traceback() after starting `R --vanilla': > library(eda) > example(medpolish) mdplsh> deaths <- rbind(c(14, 15, 14), c(7, 4, 7), c(8, 2, 10), c(15, 9, 10), c(0, 2, 0)) mdplsh> dimnames(deaths) <-

Hi all: following the previous discussion, it looks like plot(x) with y=NULL still does not work correctly. If one tries for example plot(1:5) it works, but already for plot(runif(100)) it does not. I posted the proposed correction for plot.POSIXct and plot.POSIXlt before. Please voice your opinions whether the following fix for plot.default could be reasonable? I include the full function and

I have a need to build a time series and there are a couple of aspects about the time series object that are confusing me. First it seems that ts.union is not doing what I would expect. For example: x0 <- rep(0,10) x1 <- rep(1,10) xt0 <- ts(x0, frequency=10) xt1 <- ts(x1, frequency=10) st2 <- ts.union(xt0, xt1) > xt2 Time Series: Start = c(1, 1) End = c(1, 10) Frequency = 10

A general problem i run into, i know there must be a simple solution. I like to create a variable by appending a 1 for example, (i need to loop later on from 1 to X, thus the reason for this). So i assign the variable vplot with this value, however it has quotes and when i use it in a barplot, it throws an error. but the tcenter$X1 does exist, its an element of a data frame. So if i type

Hello: I use R with MAC I have a simple data table, numeric and text columns, named dt. The table is imported through read.csv from a csv file. Row numbers are automatically assigned, header is set to TRUE. there are 599 rows and several columns. I am trying to plot using the stripchart command: one numeric variable (say dt$fnatg) vs a text column (say dt$pat). dt$pat contains one of 3 values:

Hi, I'm using R version 1.2.0 (2000-12-15), on RedHat Linux 6.2 (kernel 2.2.14). The following command ought to plot a straight-line on a log-log graph but instead plots two line segments, both with the wrong slope: plot(c(1,10,100),c(100,10,1),type="l",xlim=c(1,20),ylim=c(1,20),log="xy") Only clipped lines seem to have this problem. Changing to type "b" or

Hi, When I place a legend on a plot it looks exactly as I intended on the screen. However, almost always, when I export this to postscript file, the legend's text protrudes through the legend's frame (the latter being placed correctly). See the appended example code. I can send the EPS file as well for those that are interested (<4 kb; <200 lines). I found nothing in the FAQS,

Hello, I'm pretty new to R. Basically, how do I speed up the for loop below. Or better yet, get rid of the for loop all together. objective: plot two data sets column against column by index. These data sets have alot NA's. Some columns are all NA's. I need the plots to overlay. I don't like the plots in matplot(). Needs to be much faster than the code below... #simple sample

I have a data frame x that came from read.csv. It seemed to read in ok but then I tried doing some plotting of the values and ran into difficulties. The plot command seems to be plotting factors instead of the values. How do I get rid of these factors ? The plot command I use is : plot (x$dat, x$TX, type='l'). I also tried ...plot(x$dat, levels(x$TX), type='l) but got an error :

Hi all, I'm trying to get the value of y when x=203 by using the intersect of three curves. The horizontal curve does not meet with the other two. How can I rectify the code below? Thanks Muhammad ts <- 1:10 dd <- 10:1 ts <- seq(200,209,1) dd <- c(NA,NA,NA,NA,1.87,1.83,1.86,NA,1.95,1.96) plot(ts,dd,ylim=c(1.5,2)) abline(lm(dd~ts),col="blue",lty=2)

The following code demonstrates an annoyance with plot.lm(): library(DAAGxtras) x11(width=3.75, height=4) nihills.lm <- lm(log(time) ~ log(dist) + log(climb), data = nihills) plot(nihills.lm, which=5) OR try the following xy <- data.frame(x=c(3,1:5), y=c(-2, 1:5)) plot(lm(y ~ x, data=xy), which=5) The "Cook's distance" text overplots the label for the point with the

Hello, I am working on a project to create some scatter plots. I have syntax for 26 plots, and 22 of them display as they should. But here, for example, is a sample of the command syntax I am using: good <- complete.cases(affect1,adh1scr) plot (jitter(affect1,2.0),jitter(adh1scr,1.0),xlim=c(1,35),ylim=c(1,35),pch=1 6, main='Adherence Score by Affectiveness Level - Visit 1',

Hi, I'd like to produce a marginless or zero margin plot so that the pixel coordinates represent the mathematics. xy<-data.frame(x=c(0,1,1,0,0),y=c(0,1,0,0,1)) png('junk.png',width=300,height=300) par(mar=c(0,0,0,0)) plot(xy$x,xy$y,xlim=c(0,1),ylim=c(,1)) dev.off() The resultant file has about a 10 pixel margin around these lines, and I'm not sure what parameter or function

Full_Name: Joseph Amuah Version: 2.7.0 (2008-04-22) OS: Windows Submission from: (NULL) (205.207.78.4) I used the plot function to create some graphs but wanted to add soem restrictions. A set of warning were produced even though the plot worked fine. Can these warnings be cleaned up? Here is an example: *************************************** > plot(xx$month, xx$log10RR, xlab="",

Dear All, I've tried to add axis limit ( e.g. ylim=c(0,50)) to the log-log plot, but it turn out to be error (see below). Any solution is much appreciated. > plot(maxsd$tph,maxsd$qdbh,log="xy",xlab="Stand density(trees per ha)",ylab="Quadratic mean dbh (cm)",ylim=c(0,50)) Error in plot.window(xlim, ylim, log, asp, ...) : Infinite axis extents

Hi all, I'm faced with a problem applying the sp package: The projection argument in readShapePoly(Shapefile,proj4string="CRS class argument") e.g.: CRS("+proj=aea +lat_1=46 +lat_2=73 +lat_0=60 +lon_0=84 +x_0=0 +y_0=0 +ellps=clrk66 +units=m +no_defs") doesn't have any impact on the plotted object. I also tested the simple example: xy = cbind(x = 2 * runif(100) -
