I'm new to LaTeX and trying to format my Honors Thesis, which has very specific formatting rules to prepare the manuscript for publication. For instance, on the Abstract page, I am required to place 3 blank lines above and below my name and degree information. At the moment, this is the code I have for the abstract page:
\newpage
\begin{center}
\vspace*{1in}
ABSTRACT \\
\vfill
\singlespacing
TITLE SINGLE-SPACED IN ALL CAPS, SAME SIZE AS THE REST OF THE TEXT
\vfill %Should be 3 blank lines here.
\doublespacing
My name \\
My department \\
My degree
\end{center}
\vfill %Should be 3 blank lines here.
Put text of the abstract here.
%The abstract must not exceed 250 words.
As you can see, right now I'm just using the \vfill command, which I think looks spectacular but doesn't fulfill the formatting requirements exactly (although it gets pretty close when the abstract is 250 words). I've considered using the \vspace{} command, but I don't know how long 3 lines of text in Times New Roman size 12 font would be. Right now I'm using TeXShop to edit this document, which is a .Rnw file (I'm going to use Sweave). Right now, the default spacing is double-spacing (Most of the thesis is required to be in double-spacing) using the setspace package.
\vspace{3\baselineskip}\vspace{-\parskip}should work. But your center-environment will add some space, use better\centeringif you want to avoid this. – Ulrike Fischer Jul 18 '12 at 15:08
