Hi,
is there a specific reason to use "shift"? I mean, you could easily
achieve what you described by simple indexing:
--- snjp ---
for (i in 1:10) {
cat("x[i,num]",x[i,"num"],"\n")
# Get previous value of x[i,"num"]
zoop<-x[i-1,"num"] # NB! Returns "integer(0)" for ro
I need to write code that will give me the previous value of from a data.frame.
I have written the following code using the shift function from data.table . It
does not work. I hope someone can help me correct the code.
###

Dear Michael,
Isn't the axis() function what you're looking for?
plot(rnorm(10), rnorm(10), axes=FALSE)
axis(1)
see help(axis)
Yours.
Olivier.
