conditional value assignment
Dear R-Help,
I am trying to compute a new variable, let's call it "target cannon orientation (tco)" based conditionally on old variables, "TargetColor," "CannonOriB," and "CannonOriR." For every case in the data set, if TargetColor is "B" then I want tco to equal the value for that case of CannonOirB, else CannonOriR. I've tried writing for loops and functions that I can feed to sapply. I suspect there must be a simple solution but I cannot seem to get either...

transposing data
...ed at each combination of each
level of all the variables listed in the timevar argument:
exp1.r5.wide <- reshape(exp1.r5, idvar="Subject", direction = "wide",
sep = "", v.names="RT", timevar = c("CannonAngle", "CannonOriB",
"CannonOriR", "nRedPellets", "TargetColor", "tbearing"))
Instead what I get is Subject plus six variables that are some sort
of conjunctions of all the levels of each of the variables I want.
Instead what I want is Subject plus up to 1,008 variables encoding RT
at ever...
