[R] Fitting a sine wave using solver

I have several sets of oscillation data and would like to estimate the 
parameters of a sine function to each set (and hopefully automate 
this).  A colleague provided an excel sheet that uses solver to minimize 
the RSS after fitting the sine function to each data set, but this 
cumbersome and difficult to automate.  Is there a method in R for 
fitting a given sine function to a supplied data using maximum 
likelihood estimation (or minimizing the RSS).  Thanks in advance.
