I have tried running the following equation: 

modruns2 <- glmulti(SRI ~ TVIS + SNH3000 + BU1000 + TBE250 + TS3000 + TAB3000 +
                    PELHL1000 + SR250 + SW250, data = data1, family = quasipoisson,
                    glmulti-cvalue = 6.219132, level =1, maxsize = 4, crit = qaicc)

And it comes up with the error:

Error: unexpected '=' in "modruns2 <- glmulti(SRI ~ TVIS + SNH3000 + BU1000 + TBE250 + 

TS3000 + TAB3000 + PELHL1000 + SR250 + SW250, data = data1, family = quasipoisson, glmulti-

cvalue ="

I have been trying to follow http://cran.r-project.org/web/packages/glmulti/glmulti.pdf & http://vcalcagnoresearch.wordpress.com/package-glmulti/

But it seems I may be specifying the c-hat incorrectly.

Any help?

  • there doesn't seem to be a `glmulti-cvalue` parameter in the documentation. However, the error is weird. Try `?glmulti-cvalue` and maybe try that as a function if it exists. – LyzandeR Jan 09 '15 at 11:19
  • add this `setOption(“glmulti-value”=6.219132)` before your code and then run your `glmulti` function without the `glmulti-cvalue` parameter. – LyzandeR Jan 09 '15 at 14:28
  • I have tried running that before > setOption(“glmulti-value”=6.219132) Error: unexpected input in "setOption(“" – user13641 Jan 09 '15 at 14:32
  • Hmmm I don't know what else it might be then I m afraid... I read that from the second link you provided. If I where you I 'd try to find that variable in the source code and see if it is there, and how it is calculated. Then maybe try and change it in the code... – LyzandeR Jan 09 '15 at 14:35
  • read this one too: http://stackoverflow.com/questions/25889234/error-unexpected-symbol-input-string-constant-numeric-constant-special-in-my-co – LyzandeR Jan 09 '15 at 14:37
  • This looks like a syntax error. – LyzandeR Jan 09 '15 at 14:38
  • yep. remove the hyphen `'-'` and try again. I think that's causing the issue. it probably reads it as minus – LyzandeR Jan 09 '15 at 14:41

Install the package named R.utils. What LyzandeR suggests was correct. But instead of 

setOption('glmulti-cvalue'=6.219132)

use

setOption('glmulti-cvalue',6.219132)

I had the same issue, and I found answer in an example on this page.
