Delete a group of selected variables

This code

d <- 5
for(i in 1:10) { 
   nam <- paste("S", i, sep = "")
   assign(nam, rnorm(3)+d)
}

builds variables A1, A2,A3...A10 changing variable name in a for loop. My question is: how do i delete all these variables (with only one instruction) from memory without touching the other environment variables? (I'm using RStudio)

If we want to remove those variables, just use the same syntax with paste and as paste is vectorized it can create a vector of object names which can be fed into the rm with list argument

rm(list = paste0("S", 1:10))
