How to use termstrc functions?

Thanks for the help. RATING & NAME are not required for this call as
par documentation. About the CASHFLOWS I'm not sure as I'm going to
call create_cashflows_matrix which is supposed to return me the
cashflow matrix. Do I still need to have the CASHFLOWSlist in the
structure?

Besides needing a grouped structure and not calling that function  
with a
group name, your sub-structure does not seem complete when compared  
with the
AAA group within the example dataset;

Here it goes -

MATURITYDATE<-as.Date(c("20081231","20101231"),"%Y%m%d")

mybonds <- list(ISIN,MATURITYDATE,STARTDATE,
COUPONRATE,PRICE,ACCRUED,TODAY)
names(mybonds) <- c("ISIN","MATURITYDATE","STARTDATE","COUPONRATE",
"PRICE","ACCRUED","TODAY")
allbonds <- list(mybonds)
names(allbonds)<-c("mybonds")
create_cashflows_matrix(allbonds)


I also tried -

library(termstrc)
data(corpbonds)
create_cashflows_matrix(corpbonds)

Your collection of bonds need to be organized in groups and the  
call to
create_cashflows_matrix needs to call those groups by name. In the  
case of
the corpbonds dataset, this call gets you output:

create_cashflows_matrix( corpbonds$AAA )

Both result into the same error - Error in as.vector(x, mode) :
invalid 'mode' argument.

I'm trying to use the package termstrc. However I cannot figure  
out
how to invoke helper functions like create_cashflows_matrix &
create_maturities_matrix. Even when I try to invoke those with  
the
data supplied with the package (say, corpbonds), it throws error
saying "Error in as.vector(x, mode) : invalid 'mode' argument".  
Can
anybody provide some working example for these?
I'm on Windows XP and using R-2.7.2 + termstrc 1.1.
