[R] standard deviation

[eliza botto]

Dear useRs,
Is there a direct command in R to calculate standard deviation of BURR distribution in R? I know the direct function in VBA and worksheet..... but is there a similar function in R?
VBA
=BurrStdev(k,alpha,beta,[gamma])
Worksheet:
=BurrStdev(k;alpha;beta;[gamma])=DistStdev("Burr(k;alpha;beta;[gamma])")
Thankyou very much in advance...
