dFDRscore is supposed to take as input a vector of fdr, which
are transformed into scores according to log-likelihood ratio between
the true positives and the false positivies. Also if the FDR threshold
is given, it is used to make sure that fdr below threshold are
considered significant and thus scored positively. Instead, those fdr
above the given threshold are considered insigificant and thus scored
a vector containing a list of input fdr
the given FDR threshold. By default, it is set to NULL, meaning there is no constraint. If given, those fdr with the FDR below threshold are considered significant and thus scored positively. Instead, those fdr with the FDR above given threshold are considered insigificant and thus scored negatively
logical to indicate whether the scatter graph of scores against p-values should be drawn. Also indicated is the score corresponding to the given FDR threshold (if any)
scores: a vector of scores

# 1) generate data with an iid matrix of 1000 x 9 data <- cbind(matrix(rnorm(1000*3,mean=0,sd=1), nrow=1000, ncol=3), matrix(rnorm(1000*3,mean=0.5,sd=1), nrow=1000, ncol=3), matrix(rnorm(1000*3,mean=-0.5,sd=1), nrow=1000, ncol=3)) # 2) calculate the significance according to SVD # using "fdr" significance fdr <- dSVDsignif(data, signif="fdr", num.permutation=10) # 3) calculate the scores according to the fitted BUM and fdr=0.01 # no fdr threshold scores <- dFDRscore(fdr) # using fdr threshold of 0.01 scores <- dFDRscore(fdr, fdr.threshold=0.1, scatter=TRUE)
