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.
