Replace values in a vector
Hi all,
I have a vector like this:
x<- c(0.7, 0.1, 0, 0.2, 0.2, 0, 0, 0 , 0, 0.4, 0, 0.8, 1.8)
I would like to replace the zero values with the first previous non zero value.
my returning vector should look like this:
y<-c( 0.7, 0.1, 0.1,0.2,0.2,0.2,0.2,0.2, 0.4, 0.4, 0.8, 1.8)
How can I do this in R without using for loop?
Thank you
