legends on the outside of the "box"
Hi R People:
Here is a simple set of commands:
>x1 <- 1:10
>x2 <- sqrt(x1)
>plot(x1)
>points(x2,col="red",pch=3)
>legend(2,8,legend=c("First","Second"),col=c("black","red"),pch=c(1,3))

Fine.
Now, I would like to put the legend box on the outside of the plot itself,
perhaps in the lower
left hand corner.

Off topic -2 Ln Lambda and Chi square
Dear R :
Sorry for the off topic question, but does anyone know the reference for
the -2 Ln Lambda following a Chi Square distribution, please?
Possibly one of Bartlett's?
Thanks in advance!

str and Surv objects

I used the "Surv" function to produce the following object:

>str(a)
Error in "[.Surv"(object, 1:ile) : subscript out of bounds

Why does str(a) give an error, please? Or did I do something wrong?

ROracle and vector elements
Hi there!
Is ROracle available for Windows, please?
I found a download site, but it's really for UNIX/Linux.
Here is a "thought question", please: Why do the vector elements start at
location 1 rather than zero, as C does?
Thanks in advance!

Changing zeros to NAs in a data frame

I have a data frame with some columns that are numeric and some which are
factors.
There are zeros in the numeric columns and I would like to change them to
NAs. However, there are zeros in some of the factor columns, and I would
like them to be left alone.
Is there a "global" way to do this, please? I was thinking about use the

subsets in data frame
Hello R People:
I have a data frame with 2 numeric variables and 1 factor.
There are 3 levels of the factor.
I would like to get sums/means/etc of the numeric variables with respect to
the factor level.
I tried "table" and "subset" but have not hit upon a solution.
I thought maybe "apply" would be the answer but can't figure out how to
break out by factor.

more on apply on data frame
Hi R People:
Several of you pointed out that using "tapply" on a data frame will work on
the iris data frame.
I'm still having a problem.
The iris data frame has 150 rows, 5 variables. The first 4 are numeric,
while the last is a factor, which has the Species names.
I can use tapply for 1 variable at a time:

maybe I left out something.

[gently off topic] arima seasonal question
Hello R People:
When using the arima function with the seasonal option, are the seasonal
options only good for monthly and quarterly data, please?
Also, I believe that weekly and daily data are not appropriate for seasonal

Is that correct, please?

Ok so far.
Now I would like to plot this series with a certain y limit:
