The easiest way to answer questions like this is to use help.search()
first.  In some cases the functions are in a package that you haven't
installed or are not well indexed, so you have to ask, but in this case:

R> help.search("loess")
Help files with alias or title matching `loess',
type `help(FOO, package = PKG)' to inspect entry `FOO(PKG) TITLE':

panel.functions(lattice)
                        Useful Panel Functions
prepanel.functions(lattice)
                        Useful Prepanel Function for Lattice
loess(modreg)           Local Polynomial Regression Fitting
loess.control(modreg)   Set Parameters for Loess
modreg-internal(modreg)
                        Internal modreg functions
predict.loess(modreg)   Predict Loess Curve or Surface
scatter.smooth(modreg)
                        Scatter Plot with Smooth Curve Fitted by Loess
stl(ts)                 Seasonal Decomposition of Time Series by Loess

R> help.search("lowess")
Help files with alias or title matching `lowess',
type `help(FOO, package = PKG)' to inspect entry `FOO(PKG) TITLE':

lowess(base)            Scatter Plot Smoothing
