R help - Feb 2015 - my code in Metro_Hastings

Hi again :)
my code is in the attachment file
the problem I think in the :



mcmc_r=Metro_Hastings(li_func=baysianlog,
pars=c(1,1,1),par_names=c('alpha','gamma','delta'),data=x
)


because  I did not write the prop_sigma because I don't know how can I
calcalute the covariance matrix.
 
somebody told me to compute the cov without itreation then  add the reasulting
cov matrix to metro hasting using itreation
but it also gave me  an error 
 
Can you check my code and correct it please ?? 
 
Thank you,
Sara

No sign of your code Saral.

Probably the best way to send it is a .txt file. That usually gets through.
R-help is very fussy about what types of files it lets through
