how to pass more than one argument to the function called by lapply?
Dear R helpers:
I wonder how to pass more than one argument to the function called by
lapply.
For example,
#R code below ---------------------------
indf <- data.frame(id=I(c('a','b')),y=c(1,10))
#I want to add an addition argument cutoff into the function called by
lapply.
outside.fun <- function(indf, cutoff)
{
unlist(lapply(split(indf, indf[,'id']),

coercing a list to a data frame, lists in foreloops
I have a set of time-series climate data with missing entries. I need to add
rows for these missing entries to this data set. The only way I know to do
this is unsing a foreloop, but this won't work on a list. I've tried to
convert the list to a data frame, but that won't happen, either.
I want to fill rows in this table:

different interface to by (tapply)?
dear R experts:
has someone written a function that returns the results of by() as a
data frame? ??of course, this can work only if the output of the
function that is an argument to by() is a numerical vector.
presumably, what is now names(byobject) would become a column in the
data frame, and the by object's list elements would become columns.
it's a little bit like flattening the by()

Centering multi-line strip text in lattice
I'm having trouble centering multi-line strip text in lattice. As the
code below demonstrates bounding box of the text is centered within
the strip, but the first line isn't centered in relation to the longer
second line. The "adj" argument to par.strip.text doesn't seem to do
much. Suggestions?
a=data.frame(
x=rep(1:10,2)

chron: parsing dates into a data frame using a forloop
I have one data frame with a column of dates and I want to fill another data
frame with one column of dates, one of years, one of months, one of a unique
combination of year and month, and one of days, but R seems to have some
problems with this. My initial data frame looks like this (ignore the NAs in
the other fields):

question about rolling regressions
Hi All,
I am using R 2.11.0 on a Ubuntu machine. I have a time series data set and
want to run rolling regressions with it. Any suggestions would be useful.
Here are the details:

differences:

emp <- ts(data$ALLEMP, start=1948, frequency=1)

problem with "dynformula" from "plm" package [RE-POST]
Hello list,
I'm following the paper (http://www.jstatsoft.org/v27/i02/paper) on
how to use "plm" to run panel regressions, and am having trouble with
what I believe should be something very basic.
When I run the command (p.9 in the paper):

I see:

Text wrap
Hi everyone.
I have a long label that I would like to split. I found that I could use
"strwrap" for simple text. However, this is not working with this label:
str = expression(paste("< 20 ?m phytoplankton ","(cells ? ",mL^-1,")"))
plot(...., ylab = strwrap(str,20),...)
I suspect this is because I'm using "expression" for form my label.

Efficient way to determine if a data frame has missing observations
I have a data set covering a large number of cities with values for characteristics such as land area, population, and employment. The problem I have is that some cities lack observations for some of the characteristics and I'd like a quick way to determine which cities have missing data. For example:

abbreviate or wrap dimname labels
For a variety of displays (mosaicplots, barplots, ...)
one often wants to either abbreviate or wrap long labels,
particularly when these are made up of several words.
In general, it would be nice to have a function,
abbreviate.or.wrap <-
function(x, maxlength=10, maxlines=2, split=" ") {
}
that would take a character vector or a list of vectors, x,
and try to abbreviate or wrap

Wrap names.arg text in barplot
Hello!
Does anyone know of a handy way to wrap the names.arg text in a barplot?
I'm creating a bar plot with rather long labels; I can adjust the margins,
but I'd also like to have the text wrap to about 4cm. Thanks!

How do I wrap a long mixed text/math expression in an axis label?
I would like to wrap a y-axis label onto two lines. My label is an expression
containing both text and math symbols. I have looked at plotmath,
strsplit(), strwrap(), deparse(), do.call(), substitute() and bquote().
Based on previous posts, I can get plain text to wrap. However, when I try
these methods on my label, the exact string is returned, rather than
evaluating the math symbols.
