[SITI AISYAH ZAKARIA]

Hi,

Can anyone help me how to solve this problem?

 #calculation of confidence intervals
1. > nc <- 10000
2. > M1 <- matrix(rfrechet(nc*nobs),nrow=nobs,ncol=nc)
3. > M <- t(apply(M1,2,sort))
4. > E <- envelope(mat=M) #compute 95% confidance bands
*Error in envelope.matrix(mat = M) : rvals must be supplied*

My problem is after I run my coding in line 4 the error is highlighted red
is come out. I don't know how to solve it. Please help me.
