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 30    ...

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...

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: "Error en diff(df$dif): error in evaluating the argument 'x' in selecti...

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
