Have a look at fCover from RStoolbox. It does just that.<br>

<p class="MsoNormal"><span lang="EN-US">I am trying to look at
the
differences in land surface temperature between different
vegetation types. For
example, I have a Landsat land cover map with 30-m
resolution and I want to
calculate the fractional cover for each vegetation class
(forests, grasslands
and croplands etc.) matching MODIS swath and do a linear
regression analysis
linking land cover percentage with the corresponding MODIS
LST for each 1-km
resolution pixel. Therefore, the fractional changes will be
calculated by
computing at 30m the proportion of each vegetation class
(e.g. forest) that
occupy each MODIS 1km grid cell, but I hardly found any
practical tutorial
using R to achieve this, so any advice on it will be
appreciated!</span></p>

<p class="MsoNormal"><span lang="EN-US">Further, after
calculating the fractional
change in vegetation with analogous changes in MODIS LST, I
want
to do the linear regression for LST as a function of the
fractional changes but
also I haven't found an effective way to process it in R. I
would also be grateful if you
can give some practical advice on it.</span></p>
