Dear R users,

I have two irregular time series say x and y. Each series is supposed to
cover 20 years. The data looks, for instance:
x<-c(200,178, 330, 127, 420) ## only 5 observations out of the expected 20
annual values
y<-c(0.35,-0.18,-0.54,0.78,1.7,-1.1,0.2,1.9,0.49)### only 9 observations of
the expected 20

I need to intepolate each of the series into equally spaced 20 points. Is
there a function and library in R to do this please?

Many thanks

Tsegaye
