similar to: par("yaxp") linear versus log tick mark coordinates

Full_Name: Drew Tyre Version: 1.4.0 OS: Win 2000 Submission from: (NULL) (140.253.74.225) When creating a rather complex plot, the resulting figures 'shrink' when either copied to the clipboard or saved as a metafile using the GUI menu. Also saving as postscript or pdf causes the same problem, as does printing the figure directly from the graphics window. Only the figure areas shrink,

Dear all, I'd like to know how I could compute the parameters "yaxp" and (the y components of) "usr" without having to plot the data first. Note that "ylim" is /a priori/ fixed. The aim is to automatically adjust the parameter "mgp" without having to make the plot twice. Then, with "yaxp" and "usr" known, it should be easy to

R 2.10 Windows 7 I am trying to plot three graphs on top of each other. I need to have the axises perfectly aligned. For some reason the ticks on the y axes are slightly off so they do not perfectly align. Can someone tell me how I can get the to overlay each other perfectly? I thought the yaxp parameter would solve my problem, but it does not. My data and code follows: >

Good day, I'm trying to get more time series in one plot. As there are bigger differences in values of variables I need logaritmic y axis. The code I use is the following: nvz_3_data <- read.csv('/home/tomas/R_outputs/nvz_3.csv') date <- (nvz_3_data$date) NO3 <- (nvz_3_data$NO3) NH4 <- (nvz_3_data$NH4) date_p <- as.POSIXct(date, "CET") par(mfrow=c(2,1), ylog

Hi, I'd like to change the y-tickmarks of a boxplot. But it doesn't work with yaxp (like I would do it in a plot-function). Can someone help me out?

Hi ! I need a plot for data extending over several orders of magnitude on the y axis. The following command generates a nice looking semi-log plot for my data: plot(x,y,log="y",type="l",lty=3, ylim=c(0.01,2),yaxp=c(0.01,1,1),las=1) I would appreciate having also minor tick marks in-between the 3 major ticks obtained with the above command. The "minor.tick" function

In <R 1.8.1 the following fragment worked properly, now (1.8.1) it creates the following warning/error: Any advice appreciated. stt <- data.frame() # load all datasets into a dataframe for (ds in 1:n) { stt[ds] <- as.matrix(read.table(fileList[ds])) } -- > stt <- data.frame() > # load all datasets into a dataframe > for (ds in 1:n) { + stt[ds] <-

Hello, I have been a long-time Traditional graphics user and now moving to try Lattice graphics. At the moment I cannot figure out how to place minor tick marks in a figure made with Lattice's xyplot(). In Traditional graphics, after calling plot() I would make two calls to axis(). >From the manuals and help documentation I learned that 'scales' takes multiple 'at'

There is still issues with the reversed y-log scale plot: # Test case A: works as expected plot(10:100,log="y",ylim=c(100,11)) grid() par("yaxp") # Test case B: grid does not have horizontal lines; par("yaxp") is different plot(1:100,log="y",ylim=c(100,10)) grid() par("yaxp") In the second test case, axTicks for the horizontal lines (in

Is there a list of all contributed R libraries available through CRAN? Ideally it would include a one or two line description. I am looking for a packages() command similar to library() but that would access the CRAN repository and provide a listing of the current libraries, and version. example: http://www.cpan.org/modules/01modules.index.html

I am rendering a plot using boxplot, mtext, abline, etc. The X11 view of the plot looks correct. When I change to the png device to: png(filename="bxplot.png",width=640,height=640) I get half of a character label plotted in the lower left corner in the resulting .png file. The character fragment started to appear in png when I started using mtext.

Hello all- ? What I'm going for here is a stack of four time series plots that use a common X axis on the bottom plot. And setting up customized tick marks on each plot that help illustrate the respective trends. Here's my code: ? #### Start #### fig_data <- ts(read.csv("F:/mydata.csv"), start=2000, end=2010, freq=1) opar = par() plot(fig_data, ann = FALSE, plot.type =

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)

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?

Hi all, I would like to test the homoegeneity of variances between several linear model for some analysis of covariance. It seems that the Bartlett's test is a good test to use but I am having problem using with linear model and I cannot find any examples on the internet. There are some examples for comparisons of variances but not linear models. If I take the hellung data set, which is

Hi, I've been trying to use several plotting routings that make use of S's par("uin"), the number of user units per inch. For the moment I've substituted all of the occurences of this with par.uin _ function() (par("fin") / c( diff(par("xaxp")[1:2]),diff(par("yaxp")[1:2]))) This seems to work fine for my needs. -Greg

Hello: I should first apologize for the very basic question, but I ought to start from somewhere [embarrassed grin]. I am using R-1.0.0 in a Windows 98 machine to plot some graphs. I tried to apply a "zoom in" in some portions of the graph using say 'par(yaxp=c(0.35,0.40,5))' but nothing happens, no error msg, no update in the active graphics device. What should be the

Hello, I have a basic question. Sorry if it is so evident.... I have the following data file : http://ekumen.homelinux.net/mydata.txt I need to model Y~X-1 (simple linear regression through the origin) with these data : load(file="mydata.txt") X=k[,1] Y=k[,2] aa=lm(Y~X-1) dev.new() plot(X,Y,log="xy") abline(aa,untf=T) abline(b=0.0235, a=0,col="red",untf=T)

Dear all, I am new to R and to it's programming philosophy. The following function is supposed to work on a vector, but I can't figure out how to do that without looping through every element of it. Is there a more elegant way? Note: I have shortened it, so it is NOT correct from the pipe hydraulics point of view # Calculate wall friction factor # reynolds: Reynolds number # dk:

Hello Ted! Thank you a lot for your reply!!! I will try to explain again; what I want is a logarithmic scaled y-axis with the base of e (not 10). And the values I would like to use in the plot are the raw values (not transformed in any way). Do you still think that the base of log does not matter in this case (wheather it is e or 10 as a base)? Elisabeth > On 09-May-10 18:10:27, Elisabeth
