You can use sweave/knitr to get more flexibility and merge easily new plots ,old ones and texts:

\documentclass{article}
\usepackage{pdfpages}
\begin{document}
 this my plot 1:    % write some texts here
\includepdf{1.pdf} 
 this my plot 2:
\includepdf{2.pdf} 
 this my plot 3:
\includepdf{3.pdf} 
 this my plot 4:
\includepdf{4.pdf} 
 a new plot:
<>=         % chunk for new plots
x <- rnorm(100)
hist(x)
@
\end{document}
