You can try playing around with oma, omi, mai, mar, etc. in par():
myMai - par(mai)
myMai[1] - max(nchar(y))*par(cin)[1]
par(mfrow=c(2, 1),mai=myMai,oma=rep(0,4),las = 2)

Dear R users,
I've just uploaded to CRAN a new version of RTisean, the TISEAN-to-R interface.
This is now compatible with the recent, new 3.0.1 release of TISEAN [1].
This new TISEAN version is explicitely GPL-ed, and has some more
routines handling multivariate time series.
Bests,
Antonio, Fabio

Dear all
I have a problem in fitting lines() of the normal distributions
identified with Mclust on a histogram or a mclust1Dplot. Here is some
sample code to explain :
set.seed(22)
foo - c(rnorm(400, 10, 2), rnorm(500, 17, 4))
mcl - Mclust(foo, G=2)

Here is how you can convert them to a Date object:
x - c('01.03.2007','02.03.2007','03.03.2007')
y - as.Date(x, format=%d.%m.%Y)
y
[1] 2007-03-01 2007-03-02 2007-03-03
str(y)
Class 'Date' num [1:3] 13573 13574 13575

Hi,
I recently heard about application of sequencing algorithms to social

TDA.

Well, this is what I tried when reading the docs, but
mydata - read.csv(file='mydata.dat', sep = '\t', quote='',
Read the help desk article in R-News 4/1 and see
?as.Date
?strptime (for setting the as.Date format= argument)
Also, you might be interested in the zoo package
library(zoo)
?read.zoo
