```Here is a rough example of what you want. You will need to adjust the actual placement by hand by redefining the x & y values.

set.seed(100)
a <- rnorm(1000,0,1)
b <-rnorm(1000,0,2)
c <-rnorm(1000,0,3)
d <-rnorm(1000,0,4)
opr  <-  par(mfrow=c(2,2))
hist(a)
text(-3, 150, labels ="a")
hist(b)
text(-4, 150, labels ="b")
hist(c)
text(-4, 150, labels ="c")
hist(d)
text(-4, 150, labels ="d")

par  <-  opr
