Hi,
Does anyone know why the argument for x and q are different in dnorm and pnorm?
It seems like they represent the same thing?
Thanks!

See help(normal)
, which covers qnorm
and rnorm
, as well as dnorm
and qnorm
.
The q
and x
arguments are vectors of quantiles. p
is a vector of probabilites and n
is a number of observations. In each case, these are positional, so it doesn't really matter how whether identified in the argument
dnorm(x = your_vector)
is equivalent to
dnorm(your_vector)
x <- 0
dnorm(x = 0) == 1/sqrt(2*pi)
#> [1] TRUE
dnorm(x) == 1/sqrt(2*pi)
#> [1] TRUE
As for the naming of the arguments, I speculate that these arise from conventions among statisticians.
