similar to: Calling plot with a formula, from within a function, using ..., and xlim

After many hours of debugging code, I came to the conclusion that I have a fundamental misunderstanding regarding eval, and hope that someone here can explain to me, why the following code acts as it does: foo <- function(expr) { eval(substitute(expr), envir=list(a=5), enclos=parent.frame()) } bar <- function(er) { foo(er) } > foo(a) [1] 5 > bar(a) Error in eval(expr,

I have some code as shown below. Basically, I would like three boxplots to be set next to each other with no ylabels on the two "inner" plots, and I want the same x axis range on all three. However, it seems like boxplot does not respect the xlim setting. I've tried the various ways I thought would work (par, boxplot(...xlim=)) but none of them seem to work. I then tried plot.window,

In plot(), when using option asp=1 the xlim and ylim have no effect because they are changed changed in order to fill the whole plot region. Is there a way to automatically set xlim and ylim when asp has been set to 1? For example: #This is a box of the plot ranges I want: boxxy=rbind(c(-1,2),c(-1,-1),c(1,-1),c(1,2),c(-1,2)) #Without asp=1 I get what I want (i.e. I can't see the box because it

I have the following relatively simple problem. Say we have three factors, and we want to create a cross-tabulation against each of the other two: x <- factor(rbinom(5, 1, 1/2)) y <- factor(rbinom(5, 1, 1/2)) z <- factor(rbinom(5, 1, 1/2)) table(x,y) table(x,z) This looks like: y x 0 1 0 2 0 1 1 2 z x 0 1 0 1 1 1 2 1 I would like to get (surely this will

I just acquired a copy of "Statistical Models in S", I guess most commonly known as the "white book", and realized to my dismay that most of the code is not directly executable in R, and I was wondering if there was a source discussing the things that are different and what the new ways of calling things are. For instance, the first obstacle was the solder.balance data

All, Very basic question I can't seem to find the answer to: plot(0:10, 0:10) The axes intersection is not aligned at (0,0) in the lower left. How does one force this? I searched for graphical parameters under par(graphics) but can't seem to find it. Thanks! David

Greetings, I am trying to add a boxplot to the bottom of a histogram, right between the histogram bars and the x axis. Here is the code I am using at the moment (the par line is probably not relevant for our discussion): hs <- hist(x, breaks = 20, plot = F) par(mar = c(3,3,2,1)) hist(x, breaks = 20, main = NULL, ylim = c(-2, max(hs$counts))) boxplot(x, horizontal = T, axes = T, add =

Dear R-Help, I'm new to R and struggling with weighting data when I run regression. I've tried to use search to solve my problem but haven't found anything helpful so far. I (successfully) import data from SPSS (15) and try to run a linear regression on a subset of my data file where WEIGHT is the name of my weighting variable (numeric), e.g.: library(foreign)

I have a data frame named "database" with panel data, a little piece of which looks like this: Symbol Name Trial Factor1 Factor2 External 1 548140 A 1 -3.87 -0.32 0.01 2 547400 B 1 12.11 -0.68 0.40 3 547173 C 1

Hello all, I ran into the following, to me unexpected, behavior. I have (for reasons that don't necessarily pertain to the question at hand, hence I won't go into them) the need/desire to use an empty string for the name of a vector entry. Perhaps I did not read ?"[" very carefully, but it seems to me that he following lines should return "1" at the end:

Hello, new to the list, first message. This question perhaps might be more appropriate to R-sig-teaching, and I'd be happy to take it there if this is not the right place for it. I am teaching applied statistics at a small liberal arts college with limited resources, and we are currently using SPSS for our courses. Mainly the reason for this, as I understand it, is that this is what

Hi, I'm looking for some way to pick up the numbers which are contained and buried in a long character. For example, outtree.new="(((B:1204.25,E:1204.25):7581.11,F:8785.36):8353.85,C:17139.21);" num.char =

Full_Name: Steve Ellison Version: 2.4.1 OS: Windows, Linux Submission from: (NULL) (194.73.101.157) bxp() allows specifcation of box locations with at=, but neither adjusts xlim= to fit at nor does it respect xlim provided explicitly. This is because bxp() now includes explicit xlim as c(0.5, n+0.5), without checking for explicitly supplied xlim (or ylim if horizontal). This also prevents

Dear R-developers, A student asked me today of how to specify the limits of the x-axis. I knew that he should use xlim, but I tried to encourage him to have a try himself with the various help functions. I do not judge if he used the correct search strategy or right key words, but anyway here is what he tried: he looked at ?plot. There xlim is not mentioned. He checked ?par. There you find

hello all sorry for the following "none" R related question. does anyone know of a reference to calculate the following identity: |I + ABC| where I is an identity matrix and A, B,C may not have to be square matrices? you help will be greatly appreciated. H. V. Henderson; S. R. Searle SIAM Review, Vol. 23, No. 1. (Jan., 1981), pp. 53-60. provides a result to

Sorry if this is already answered somewhere, but I could not find it. I have two vectors, x,y, of different length, and I want to recycle the smaller one (whichever one it is) until they have the same length. I was wondering if there is a anything better than something like: x<-1:3 y<-1:10 x<-rep(x,length=max(x,y)) y<-rep(y,length=max(x,y)) or some variant of that using if to

Hi all, I'm trying to write a plugin for R Commander, following the model of the TeachingDemos plugin. I am struggling trying to even add items by editing the menus.txt file. I would welcome any help from anyone who has messed with it. Essentially the problem I am having is: I cannot create a submenu to a newly created menu. Here is what the menus.txt file looks like: # type

Since we're on the topic of book reviews, I just received Phil Spector's new R book called "Data Manipulation with R" and it is also quite a nice book. I haven't gone through it all and I won't give a detailed review but I have gotten a lot out of the first 100 pages that I have read. Note that I've been using R for almost 1.5 years so , for me, it's a

hi, i am using par(mrow=c(6,6)) function to get 6x6 plots on one screen. the problem that i am having is that the axis tick labels are far away from the ticks and going into previous plots (see attached figure). i need to know how can i reduce the distance between the ticks and their values (y axis values).the part of the code that i am using (after reading in the data) to create the top row is:

Hello, I just discovered that I cannot close the Excel application and task manager shows numerous copies of Excel.exe I tried both x$Quit() # shown in the rcom archive and x$Exit() and Excel refuses to die.
