# compareCoefs

##### Print estimated coefficients and their standard errors in a table for several regression models.

This simple function extracts estimates of regression parameters and their standard errors from one or more models and prints them in a table.

- Keywords

##### Usage

`compareCoefs(..., se = TRUE, print=TRUE, digits = 3)`

##### Arguments

- …
One or more regression-model objects. These may be of class

`lm`

,`glm`

,`nlm`

, or any other regression method for which the functions`coef`

and`vcov`

return appropriate values, or if the object inherits from the`mer`

class created by the`lme4`

package or`lme`

in the`nlme`

package.- se
If

`TRUE`

, the default, show standard errors as well as estimates, if`FALSE`

, show only estimates.If

`TRUE`

, the defualt, the results are printed in a nice format using`printCoefmat`

. If`FALSE`

, the results are returned as a matrix- digits
Passed to the

`printCoefmat`

function for printing the result.

##### Value

This function is used for its side-effect of printing the result. It returns a matrix of estimates and standard errors.
