Imposing more than one condition to if
Hi,
I have a dataset which contains several time records for a number of days, plus a variable (light) that allows to determine night time (lihgt= 0) and daytime (light> 0). I need to obtain get dusk time and dawn time for each day and place them in two columns.
This is the starting point (d):
day time light
1 1 20
1 12 10
1 11 6
1 9 0
1 6 0
1 12 0
...
30 8 0
30 3 0
30 8 0
30 3 0
30 8 8

modify and append new rows in a dataframe
My data frame shows changes on the variable act which records the consecutive duration (in seconds) of two states (wet-dry) over a few days for several?individuals (identified by Ring). Since I want to work with daytime (i.e. from dawn till dusk) and night time (i.e. from dusk till next dawn), I have to split act in two: from time[i] till dusk and from dusk until time[i+1], and from time[k] till dawn and from dawn until time[k+1].
Example:
ith row: 01-01-2000 20:55:00 act= 360 seconds
i+1th row: 01-01-2000 21:01:00 act= 30 seconds # say...

How to add instructions to a Module at runtime?
Hi all,
I'm trying to understand how the Module object works more in details, so
suppose I've an empty module and I'd like to know if it is possible to add
instructions at runtime and execute it. Is it possible to do it? Any
suggestion on how?
Thanks

modify and append new rows to a data.frame using ddply
....frame. Here is a piece of existing code that I am trying to adapt just for the daytime/night time change:
? require(plyr)
? xandaynight <- ddply( xan, .(Ring), function(df1){
? # index of day/night changes
? ind <- c( FALSE, diff(df$dif) == 1 )
? add <- df1[ind,]
? add$timepos <- add$dusk
? # rearrangement
? df1 <- rbind( df1, add )
? df1 <- df1[order(df1$timepos),]
? # recalculation of act
? df1$act2 <- c( diff( as.numeric(df1$timepos) ), NA )
? df1} )
This code produces an error message:

patch to fix non-echo tty on scp SIGINT
A long-time missing feature (or bug, depending on how you look at it) is
that a Ctrl-C at the password prompt in scp does not restore the
terminal settings, thus dropping you to the command prompt without any
keyboard echo. (A "reset" command will fix it.) This is a pretty
regular occurance for me, and some others I've talked to - usually when
you realize that the scp command you
