bioconductor: when I used the following example to do MTP analysis #data set.seed(99) data<-matrix(rnorm(90),nr=9) group<-c(rep(1,5),rep(0,5)) m1<-MTP(X=data,Y=group,test = "f.block",alternative="less",B=100,method="sd.minP") the following error information occurs: Error in "[<-"(`*tmp*`, (i - 1) * l + j, value = numeric(0)) : nothing to replace with In addition: Warning messages: 1: number of items to replace is not a multiple of replacement length 2: number of items to replace is not a multiple of replacement length 3: number of items to replace is not a multiple of replacement length 4: number of items to replace is not a multiple of replacement length how to fix it? Thanks
