R help - Sep 2006 - get index of elements in vector

Hello all


Is There a fuction that return a index of a element in vector?
like this semantic example:

vector = c( 100, 200, 300 )

getINDEX( vector, value = 200 )

Thanks in advance for your attention.


Cleber Borges

look at ?which(), e.g.,

which(vector == 200)


Best,
Dimitris
