Hello all,
given two vectors X and Y I'd like to receive a vector Z which
contains, for each element of X, the index of the corresponding
element in Y (or NA if that element isn't in Y).
Example:
x <- c(4,5,6)
y <- c(10,1,5,12,4,13,14)
z <- findIndexIn(x, y)
z
[1] 5 3 NA
1st element of z is 5,
Robert,
Try
match(x, y)

Hi guys,

does exactly what I need. match() gives the values of the elements,
but not their positions.

Hi
Why you do not change date and time to POSIX object? It is simple and saves you
a lot of frustration when merging two data frames.
If you changed lightdata date and time to new column
lightdata$newdate <- strptime(paste(lightdata$date, lightdata$time, sep=" "),
format = "%d/%m/%y %H:%M:%S")

thanks for the response. stopifnot() looks almost right. it's very

The answer is essentially no, a loop is required (as best I can see),
although it can be in the form of an apply type call instead. Also,
your code will fail with a 0 index. Something like this should work:
