[R] Percentile function

[Art Salwin]

Is there an R function that inputs a value and a vector, and
returns the percentile corresponding to the value?  
Something like

pvalue<-function(x,vector){mean(x>=vector)} 

but with interpolation.

Given the above function, is there a way to do the following
without the loop:

for(i in 1:10) y[i] <- pvalue(x[i],vector)

where x and y are numeric vectors of length 10?
