layout(matrix(c(1,2,3,4,5,6), 3, 2, byrow = TRUE))
for (i in 1:6) plot(
dchisq(1:20, i*2),
main = paste("chi-square density, df =", i*2))
I do have some reservations about the validity of this approach,
however.
Also your keyboard needs some attention as well. Spacebar and shift
key function seem very erratic.
