argument "variable" is missing, with no default

When tried to use crPlot() function in car package, I had encountered this error:

m1 <- lm(socst ~ read+write, data=hsb2)
crPlot(m1)

Error in crPlot.lm(m1) : argument "variable" is missing, with no default

And the same error happens with avPlot().

From the documentation:

S3 method for lm crPlot(model, variable, id=FALSE, order=1, line=TRUE, smooth=TRUE, col=carPalette()[1], col.lines=carPalette()[-1], xlab, ylab, pch=1, lwd=2, grid=TRUE, ...)

variable: A quoted string giving the name of a variable for the horizontal axis.

Also, you should generally use 'crPlots', not 'crPlot'.
