last day of month values
-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1
I have a stock market trading values time series. What's the best way to
extract the "last day of month" values. I looked at function window() but
doesn't appear suitable for this since it expects regular dates.
Thank you.

Converting dates?
Dear R-users
I have some doubts about with converting dates...
e.g.
dates data
23/12/1975 0.8678
03/01/1976 0.8736
28/01/1976 0.765
13/03/1976 0,9654
...
I think that converting these dates can easily my plots...
is there a R function to convert these dates to
a julian dates and so plot that variables??
The help files as.POSIXlt, POSIXt and others

plot
Hello!
I use the version 1.4.0 for Windows. I have made boxplots but only half of
the symbols (three letters each) show up on the X-axis? How t can one
change their size or orientation so that all show up? I attach the pdf file
to illustrate better the problem.

covariance of equal date values
-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1
I need to count the covariance of two time series. Both of them contain
the dates' vector and vector of values. But the dates are not the same. It
means some dates of first ts are not in the second respectively. And I
need the covariance of same dates, of course.
Could anyone help me, please?
Thank you.

2 simple doubts
Hello,
I'm just start learning R/S-Plus, so I think this 2 doubts is going to
be too easy for you...
1) I couldn't discover what is the command for a concatenation of 2
variable strings.
2) For example, if I have three variable strings, and each one has the
name of a variable in a data matrix:
a<-V1
b<-V2
c<-V3
, is it possible to construct a command like this:

a R question
Dear Sir,
I have been working with R for some time now and I am very happy with
it, but I have found a problem that I could not resolve. Could you
please give me some hint about how to transform POSIX time data in
seconds to string format?. (eg. 995752800 -> year-month,day,hour,min,
sec) I tryed with Sys.time(), strptime() and date() but without success.
Thank you very much in advance

Subtitle?
Hi,
Is it possible to add a subtitle that appears directly below the main
title?
I tried the "sub" parameter, but it adds sub-title to the bottom of the
plot.
Cheers,

question about scan()
Hi,
I am using the scan function to read from a file. In
general the syntax I am using is as follows:
scan("myfile", list(a = "", b="", c="", d=""), sep=",")
The file I am trying to read contains a #< in the 'd'
field. When the file is read into an object, the d
field comes as "" for that particular string.

plot question
Hi!
I want to display 2 graphs with different number of data points on the
x-axis. The code below scales them so it seems that testtwo has the
same number of data points as testone. How can I fix that? thanks.
z<-1:50;
x<-1:100;
plot(x,testone,type="l",xlab="",ylab="",main="",lty=4,axes=FALSE,ylim=c(-1.0,1.0),cex=1);

storing large data.frame's
I am new on R, so I have a maybe naive question:
if I have many large data.frames and I use only one or two per session,
what's the best way?
If all are stored in the actual .Rdata, the system gets slow.
On the other hand, I wouldn't like to make a separate package for the
data.
Should I save it with save() and then remove it with rm() ?
Could I reload it then?
Thanks for suggestions
