RFE: vectorize URLdecode
In R 2.9.2,
> URLdecode(c("a%20b", "b%20c"))
[1] "a b"
Warning message:
In charToRaw(URL) : argument should be a character vector of length 1
all but the first element will be ignored
Could URLdecode be modified to actually process all elements of the vector, not
just the first?
Thanks in advance

Inconsistent behavior of sQuote and dQuote
Dear all
When comparing sQuote("text") and dQuote("text") on MacOS X and Linux FC4
I get an inconsistent behavior (using the new release version R-2.6.0):
sQuote: On Mac I get the correct result "'text'", but on FC4 the
incorrect result "`text?".
dQuote: On Mac I get the correct result "\"text\"", but on FC4 the
incorrect

sQuote() on zero-length inputs
It's not desperately important, but it would seem more consistent to
me if sQuote(character(0)) or sQuote(NULL) returned character(0) rather
than "??" . This could easily be achieved by putting
if (length(x)==0) return(character(0))
at the beginning ...

quote() vs quote(expr=)
Hi all,
I think there's a small buglet in quote:
str(quote())
# Error in quote() : 0 arguments passed to 'quote' which requires 1
str(quote(expr = ))
# symbol
I bring this up because this seems like the most natural way of
capturing the "missing" symbol with pure R code, compared to
substitute() or bquote() or formals(plot)$x

replace an expression with its value, or read macros
I know my subject line seems odd, but I want to replace an expression—such as a variable—with its value. For example, I want to paste() some strings together, assign the result to a variable s, then use the value of s as a variable to hold another value. Something like this:
import_subjects <- function (start, iterations) {
for (i in 1:iterations) { # iterate from start to end

using bquote to construct function
Hi, R-help,
(sessionInfo at the end)
I'm trying to construct a function using bquote and running into a
strange error message. As an example, what I would like to do is this:
z <- 2
eval(bquote(function(x, y) { x^.(z) + y }))(2, 3)
However, I get the following:
Error in eval(expr, envir, enclos) :
invalid formal argument list for "function"

?bquote
?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"

Using bquote to create names a for a list
Hello,
How would i use bquote to create names for a list.
e.g. to create list(a=10)
bquote(list(.(X)=10), list(X="a"))
does not work.
The best i could come up with is
bquote({ a=list(10);names(a)=.(X); a}, list(X="a"))
which is quite ugly.
Is there an elegant way to solve this?

Two == expressions in bquote
Hi,
I want to put text on a plot containing something like: a = b^2 = <squared numeric value of b> using bquote.
Example:
mu = 5
plot(1:10,1:10)
text(2,8, bquote(delta == mu^2)) # This works
text(2.5,8, bquote(phantom(0) == .(mu^2))) # but is unpredictable
text(2,8, bquote(delta == mu^2 == .(mu^2))) # This doesn't work
The last text function returns the error:

Hi,
I need to plot the beta as the symbol, followed by the index 3 as the title of a graph.
This code works> main= bquote(paste("Results for ", beta ==.(b1))

I tried (simplified):

Changing graphic titles when using bquote and resizing the graphic window
Dear list,
I found a strange behavior of the graphic display when using bquote to set a title to a plot. The problem arise when you manually resize the graphic window using the mouse. It happens on both quartz and x11 devices. Here's a reproducible example:
par(mfrow = c(1,3))
for (i in 1:3){
title <- as.expression(bquote(gamma[.(i)]))
plot(1:10, main = title)
}

bquote/evalq behavior changed in R-3.2.1
I am curious why you used evalq instead of eval in this code.

Use plotmath expressions read from a text file in mtext/bquote
Hello R-help List
I am writing some R scripts to create graphs of water quality trends
that will be called by a web service running R. The axis titles will

I think rapply() was changed to act like lapply() in this respect.
In R-3.1.3 we got

#[1] 18

Using bold font with bquote

I have been able to successfully turn the sigma symbol and numeric output the color blue,
but when I try to change the font of the text to bold, R doesn't seem to recognize the "font="
