Arguments

`x`	The fitted model.
`which`	The plot(s) to be drawn. Residuals vs fitted values ( `which = v1`), histogram and QQ plot of residuals (`which = 2`), Cook's distance plot (`which = 2`).
`mar`	Margins applied to each selected plot.
`...`	any other arguments to pass to `plot`

Methods (by class)

modelcheck(lm): Model checking plots

Examples

x = 1:30
y = rnorm(30)
lm.fit = lm(y~x)
# Plot resids vs fitted only
modelcheck(lm.fit, 1)

# Plot resids vs fitted, and histogram and QQ plot
modelcheck(lm.fit, 1:2)

# Plot all
modelcheck(lm.fit)
