Get number of observations from a modelSource:
This method returns the number of observation that were used to fit the model, as numeric value.
n_obs(x, ...) # S3 method for glm n_obs(x, disaggregate = FALSE, ...) # S3 method for svyolr n_obs(x, weighted = FALSE, ...) # S3 method for afex_aov n_obs(x, shape = c("long", "wide"), ...) # S3 method for stanmvreg n_obs(x, select = NULL, ...)
A fitted model.
Currently not used.
For binomial models with aggregated data,
n_obs()returns the number of data rows by default. If
disaggregate = TRUE, the total number of trials is returned instead (determined by summing the results of
weights()for aggregated data, which will be either the weights input for proportion success response or the row sums of the response matrix if matrix response, see 'Examples').
For survey designs, returns the weighted sample size.
Return long or wide data? Only applicable in repeated measures designs.
Optional name(s) of response variables for which to extract values. Can be used in case of regression models with multiple response variables.
The number of observations used to fit the model, or
