With other than vector types of argument, such as list mode arguments, the action of c() is at first sight rather different. See §.

...

Note that abs() does not work as expected with complex arguments. The appropriate function for the complex modulus is Mod().

...

numeric mode is actually an amalgam of three distinct modes, namely integer, single precision and double precision, as explained in the manual.

Note that x %*% x is ambiguous, as it could mean either or , where is the column form. In such cases the smaller matrix seems implicitly to be the interpretation adopted, so the scalar is in this case the result. The matrix may be calculated either by cbind(x) %*% x or x %*% rbind(x) since the result of rbind() or cbind() is always a matrix.

...

This ellipsis is used as a customary typographical device to mean an abridgement. This is not the case in the latter part of section.

Warning: The PostScript code produced by the postscript() device driver is not Encapsulated PostScript, and thus including it in a document electronically (as opposed to physical cut-and-paste) can be rather problematic. For this type of application, a better solution is to use the fig() driver (available from statlib) and use a conversion program (such as fig2dev to convert the resultant fig code to Encapsulated PostScript.
