R help - Oct 2008 - Suppressing error messages in a for loop

Hi,

Is there any way that I can supress error messages so that they don't stop
for loops running?

I'm using the gstat package and have created a variogram model for the
double exponential model:

    "dexp <- vgm( .5, "Exp", 10,.1, add.to = vgm(.5,
"Exp", 100))"

and fitted it using
 
    "dexp.fit <- fit.variogram(temp2, dexp, fit.method=6,
debug.level=0)"

Occasionally I get the following error message and the model doesn't fit

    "Error in if (direct[direct$id == id, "is.direct"] &&
any(model$psill <
: 
     missing value where TRUE/FALSE needed"

I don't mind that the model doesn't converge, however the error message
stops the for loop I'm running at the time (and so stops my code!).  Is
there any way that I can suppress the error message?

Sorry if this is a really simple question, I'm still new to r programming!
Best wishes
Helen Greatrex
