R help - May 2008 - autocorrelation error: cannot allocate vector of size 220979 Kb

Dear R community,



I used a linear mixed model (named lm11) to model daily soil temperature
depending upon vegetation cover and air temperature. I have almost 17,000
observations for six years.



I can not account for autocorrelation in my model, since I receive the error
message after applying the function:



update(lm11, corr=corAR1())



Error: cannot allocate vector of size 220979 Kb



Do you have any suggestions?



Thanks, Julia

More information is needed.  What is your operating system?  How much RAM do
you have?  Are there other objects in memory that you could delete to
recover some space?  What does 'str' and 'object.size' say for
the data you
are analyzing?  What does 'gc()' report  -  you may want to do this
before/after sections of code to see how memory might be growing.
