# Psych Library polychoric Function Error "You have more than 8 categories for your items, polychoric is probably not needed"

I'm new to R and running into an error with the `polychoric`

function in the `psych`

package. I'm attempting to store the polychoric correlation matrix in a data frame from using the following syntax:

`RPOL36 <- polychoric(norm.kdqol36,smooth=TRUE)`

where `norm.kdqol36`

is a data frame with vectors of ordered variables, each with 5 levels (0, 25, 50, 75, 100). Here is an example:

```
0 25 50 75 100
11962 19953 4987 12998 8261
```

Despite each variable having 5 levels, I get this error:

Error in polychoric(norm.kdqol36, smooth = TRUE) : You have more than 8 categories for your items, polychoric is probably not needed

Could there be a formatting issue causing the `polychoric`

function to read my variables as having more than 5 categories?
