Error: cannot take a sample larger than the population

Hi, In Splus7 this statement xlrmN1 <- sample(c(0,1,2),400 ,prob=c(0.02 ,0.93 ,0.05 )) worked fine, but in R the interpreter reports that the length of the vector to chose c(0,1,2) is shorter than the size of many times I want to be selected from the vector c(0,1,2). Any good reason? See below the error.

Error in sample(length(x), size, replace, prob) :
cannot take a sample larger than the population
when 'replace = FALSE'
Execution halted
So why not use replace = TRUE ?
xlrmN1 <- sample(c(0,1,2),400 ,prob=c(0.02 ,0.93 ,0.05 ), replace=TRUE)
table(xlrmN1)
xlrmN1
0 1 2
5 373 22
prop.table(table(xlrmN1))
xlrmN1
0 1 2
0.0125 0.9325 0.0550
TIA, Aldi --
