Hi Wee-Jin
you can block out bits of R code with
if(FALSE){
code not executed
}
For the line breaking, R deals with incomplete lines by not executing
the statement
until you finish it. In the function case, it waits for you to close
a bracket.
If you type:
myFunc(a=3,
b=5,
c=6,
d=7
)
pdf(sgr6100.pdf, horizontal=FALSE, onefile=FALSE,
height=3, width=3, pointsize=6)
Reducing point-size below 6 does not seem to make any difference to
the size of text and symbols. Any suggestions to get smaller font sizes?
I have never used the pointsize option. Increasing the height

I get syntax errors on both, due to the missing comma at the

Hello,
I have a simple question on the text() method in plots, e.g.:
text(3,4,adj=1,cex=1.0, expression(alpha == beta))
Jue,
On a second look, it appears that wilcox.test does report the
offset-adjusted statistic U, as also mentioned in the help page.
wilcox.test returns W=6 (instead of 12 as your example showed, unless
wilcox_test is a different function).
wilcox.test( 1:5 ~ c(1,1,0,0,0) )$statistic # or
Are you sure Fall.dat is identical on both platforms, and that dt is also?
Did you intend to ignore the cases where dt$V2 equals zero?
Try, for example,
table(which(dt[,2] == 0)) ## also ==1, ==2, ==3
unique( dt[which(dt[,2] == 0),5]## also ==1, ==2, ==3
unique( dt$V5 )

Hi,

Greetings, friends in the R community,
this is an OT question about statistics. Given four time series of
events, what possibilities do I have to test for synchronicity?
e.g.
times - data.frame(year= c(1, 2, 3, 4, 5, 6, 7, 8, 9, 10),
event.1=c(1, 0, 0, 1, 2, 4, 1, 0, 0,

Hello,
I'm a novice user trying to figure out how to retain NA aggregate
values. For example, given a data frame with data for 3 of the 4
possible factor colors(orange is omitted from the data frame), I want
to calculate the average height by color,
We have a solaris/sparc machine that has been running an old version
of R-devel: Version 2.2.0 Under development (unstable) (2005-06-04
r34577)
which was built as m64 from sources. Attempting to upgrade to 2.4.0
the configure step
goes ok, but I'm getting early on from make:
gcc -m64
If you include a conditioning factor (here it is the variable
groups) you will get more than one panel. To get loess curves for
the two groups, the easiest way is to use the type argument:
xyplot(y ~ time, groups=group,data=df,type=c(p,smooth))

Please let's not waste any time trying to figure out how to add
block comments to R. In any guise they are highly error prone.
Although its precursors (PL/I and Pascal) had block comments and did not
have end-of-line comments, the programming language Ada was explicitly
designed to have
Probably the best you can hope for is to cover
most cases. This one uses match.call and handles
a number of cases and perhaps if you spend more time
on it might be able to add some cases where it fails
such as the second L below:
f - function(x) {
if (!is.list(x)) x - list(x)

I should have mentioned is that the way it works is that
it uses the name of the list component, if any, otherwise
it uses the name of the function if its given as a number
and otherwise it uses the function itself or possibly the
name of the list.
