r - PerformanceAnalytics Numbers to Percent % -

i want know if possible make table output in r package % instead of numeric.

table.annualizedreturns(indover, rf=0)                            sp500   annualized return         0.0732 annualized std dev        0.1951 annualized sharpe (rf=0%) 0.3752 

so 1st 1 0.0732 see 0.07%

the return value function data frame, question how make column of data frame print percentage sign.

reproducible example follows.

> require(performanceanalytics) > data(managers) > tb =      table.annualizedreturns(managers[,1],rf=0) > tb                             ham1 annualized return         0.1375 annualized std dev        0.0888 annualized sharpe (rf=0%) 1.5491 

now define new class , format function displays percent sign:

> format.pc = function(x,...){sprintf('%0.2f%%',x)} > class(tb[,1])="pc" 

and now, if magic:

> tb                            ham1 annualized return         0.14% annualized std dev        0.09% annualized sharpe (rf=0%) 1.55% 

the underlying values have not been changed:

> tb[,1] [1] 0.1375 0.0888 1.5491 attr(,"class") [1] "pc" 

they in vector of new class.
