Hello Lyx-Community, I have a problem with the Lineno-Package (for Line numbering) in combination with the RevTex4(article) documentclass.
RevTex4 states that it is incompatible with the lineno-package. (http://authors.aps.org/revtex4/revtex4_faq.html). Nevertheless on http://fourforces.wordpress.com/2008/04/24/add-line-numbers-using-linenosty-in-revtex-4/ a workaround is published: It is necessary to put the Line \RequirePackage{lineno} in the Latex preamble before(!!!) the documentclass-command! My question is now: How can I add a line to the beginning of the preamble? In Lyx the use-specified commands appear always at the end of the preamble.. Thanks, Christian (Lyx 1.5.3.)
