Hey, I am trying to find some of the following functions in R packages:

MLEt

pt3

cormatrix2vector

ParameterEst

tCopula

riskBT

I have checked every package from this link:
http://cran.r-project.org/web/packages/available_packages_by_name.html but
is unable to find the above functions. These functions belong to a code for
calculating Value-at-risk and expected shortfall using copula function and
backtesting the model.

Could you please help me find these functions by naming the packages they
belong to. Its really urgent for me so please reply asap.

If required i can send the entire code for better understanding.

If this is not the right place to mail a query, please do let me know where
can I send my query, its really urgent for me.
