In ?exists it says: inherits: should the enclosing frames of the environment be searched? I believe what it is saying is that if inherits is TRUE and it fails to find the variable it will look in the parent environment and the parent of the parent, etc. (as opposed to looking in the calling frame next and the caller of the caller, etc.) Now I thought that standard terminology in R was: 1.

I noticed, what seened to me, to be odd. These produce a boxplot in the first case and a spineplot in the second case in R .2.2.0: plot(Sepal.Length ~ Species, iris) plot(Species ~ Sepal.Length, iris) What if one wants to exchange axes? Does the fact that this seemingly innocuous change result in completely different graphics make sense? Is it desirable?

Is there a place that shows how to create two plots that are stacked on top of each other where they share a common x-axis scale, but have differnt y-axis scale? Say have the following data: airquality Stack plot(airquality$Day, airquality$Wind) on top of plot(airquality$Day, airquality$Temp). I am interested in stacking the two on top of each other with no seam, or plotting the two lines with

To use the modify the solution from Tony and I so that you can pass the name of the function, rather than the function itself, like this: x <- 7 fx <- function(y) print(x*y) f <- function(fun, x) { fun <- get(fun) environment(fun) <- environment() do.call("fun",list(3)) } f("fx",2) --- Date: Thu, 11 Mar 2004 08:22:45 +0100 From:

Hi R-Experts, I'm currently using R 2.4.0 in Windows XP. I'm trying to download data from Bloomberg using the package "RBloomberg", but it fails to install the three needed packages "zoo", "chron" and 'Rbloomberg". Moreover I am not able to find "RBloomberg" package as windows binary in CRAN site as only for MAC it's given. Please

Dear All, I am trying to solve the following maximization problem with R: find x(t) (continuous) that maximizes the integral of x(t) with t from 0 to 1, subject to the constraints dx/dt = u, |u| <= 1, x(0) = x(1) = 0. The analytical solution can be obtained easily, but I am trying to understand whether R is able to solve numerically problems like this one. I have tried to find an

I noticed the following today --- str() seems to remove any extra class information added to an environment. > e <- new.env() > class(e) [1] "environment" > class(e) <- c("foo", class(e)) > class(e) [1] "foo" "environment" > str(e) Classes 'foo', 'environment' length 0 <environment> > class(e) [1]

?bquote says it returns an expression but, in fact, it typically (though not always) returns a call object: > class(bquote(a+b)) [1] "call" > class(bquote(1)) [1] "numeric"

Hi Experts, I want to see my object as below: 'C:\Program Files\R\R-2.4.0\bin\Rgui.exe' So I use the paste command. None of the below is working.

Hi all, I am using the zoo package to plot time series. I have a problem with formatting the axes. my zoo object (z) looks like the following. c1 1992-01-10 21 1992-01-17 34 1992-01-24 33 1992-01-31 41 1992-02-07 39 1992-02-14 38 1992-02-21 37 1992-02-28 28 1992-03-06 33 1992-03-13 40

Hello All, Moving from 2.5 to 2.6.2 and I was wondering if there is a preferred directory structure for using multiple environments? Does it work much different in 2.6 than in 2.5? When I made the move I assumed (I know) that my current structure and configurations would just roll over but that isn''t the case. Thanks, Jim -- You received this message because you are subscribed to the

Dear All, Is sqldf equipped with delete queries? I have tried delete queries but with no success. Thanks in advance, Paul

Good day everyone. I have a large dataset of 1 min wind speeds covering 5 years. How can I make an array of maximum daily values? The vectors I have are: 'VDATE' with dates in format '%Y-%m-%d' (like '1992-10-28') and 'WS' with wind speed data (same number of elements as VDATE). I want an array with 2 columns: Max daily wind speed and corresponding day. Has

I noticed that in "R version 2.4.0 alpha (2006-09-16 r39365)" on Windows XP that I get this error: C:\Rpkgs>Rcmd install mypkg no Perl script 'install' The same command worked with no error in 2.3.1pat. If I capitalize INSTALL it does work; however, this was not necessary previously. Note that C:\Rpkgs>Rcmd check mypkg unlike install, still works in either lower or

I have NEWS, WISHLIST and THANKS files in the 'dyn' package in the same directory as the DESCRIPTION file but I noticed that they did not survive the move to CRAN, at least on Windows. How do I incorporate them so that they are not omitted?

Hi Folks, My recent response to Laura Quinn's query about matrix subsetting reminded of a question. I wrote: iDir <- ((Winds[,20]<45)|(Winds[,20]>315))&(!is.na(Winds[,20])) Now, I find "!is.na" a bit awkward to type, so I might prefer to type it as "nis.na". While it is possible to define nis.na <- function(x){ !is.na(x) } this involves a slight

Hi I'm using R 2.0 in SuSE 9.2. When I plot data as a boxplot, the boxes appear on the plot in alphabetical order (of group) rather than the order in which they appear in the data. So far, the only thing I can do to fix this is to prefix the group labels with a,b,c...etc to trick R into plotting them in the right order. Can sorting be turned off? How should I address this sensibly? Thanks
