Although David's solution (putting the right parenthesis, which I had missed)

Could you please clarify the six elements: c(-1e-8, 0, 0, 0, 0, 1e8)?

Sorry for not being clear. I forgot to mention that the variable labels don't
really say which are categorical/continuous.
They are just I1, I2,, I459. Out of these 459 variables, most are
continuous and others are categorical.
So, the grep command won't work here.
Thanks,

Hello,
You must have a way of telling whether the variables are categorical. If
they are factors, just not ordered factors, instead of grep the
following might work.
vars.to.order - sapply(yourdata, is.factor)
And the rest should be the same.
Hope this helps,

Hello,
The format AM/PM should be for display purposes only, when you use
format() you get a variable of class character, not of classes
POSIXct POSIXt . Produce a variable y with as.POSIXct (without
AM/PM) for arithmetics and another formated for display.
Hope this helps,

Yes. That's true. All the variables are read in as numeric/integers.What I am
looking for at this moment is if any variable has less than equals to 10 unique
values (categories) then it is a factor. Can that be incorporated?
Thanks,
Debs

Thanks to both of you for your help. I think I have got what I wanted.
vars.to.order - sapply(d, FUN = function(x){length(unique(x))=10}) ## check
no. of unique values for each variable
#d[ , vars.to.order ] - lapply( d[ , vars.to.order==TRUE ], factor) ## I
didn't need this line. Is this step
Hello,
Just one more thing, you don't need an explicit test to TRUE, the two
lines below are equivalent.
d[ , vars.to.order==TRUE ]
d[ , vars.to.order ]

HI,
Just by taking David's solution:
y - as.POSIXct(paste( floor(x), round(60*(x-floor(x))) ), format=%H %M)
y1-data.frame(y,AM_PM=format(y,format=%p))
y1[3,1]-y1[4,1]
#Time difference of -40 mins
y1[5,1]-y1[3,1]
#Time difference of -13 mins
head(y1,2)
# y AM_PM
#1
# can use sprintf to convert to a number with 2 digit fractions
x - c(10.30, 11, 11.01, 11.09, 11.15, 11.59, 12, 13)
as.POSIXct(sprintf(%.2f, x), format = %H.%M)

Useful procedure to prevent loss of trailing .00's, ... but just to
clarify, sprintf never returns a numeric class object, but rather
returns a character representation of one.
Hi,
I have a laptop (Mac OS) and a remote PC (Ubuntu) and would like to do the
heavy work on the remote machine but control it via the laptop.
I managed to install ssh server and can now remotely connect to my PC via ssh
and can start an R session in the terminal.
However, I still don't quite
Given a data set with a group factor, I want to translate the numeric
variables to their
centroid, by subtracting out the group means (adding back the grand means).
The following gives what I want, but there must be an easier way using
sweep or
apply or some such.
iris2 - iris[,c(1,2,5)]

Dear users,
I'm struggling with encoding issues for documenting some functions. The Rd
format is incradible simple, however, because I'm dealing with diacritic
strings, I seted up encoding in several Rd files as latin1. Under R, using the
checks available in the package 'tools it performs

Hi Martin,
In addition to what Duncan writes: I think winscp does exactly what you
want. You can copy objects from/to linux, but also edit files from linux on
the winduts machine without explicitly copying (of course you do copy the
file, but is done automatically).
Bye
Frans

I have the same setup and do this:
- rsync all data and R scripts
- run analysis on remote server via ssh
- rsync plots and results back
