tests/testthat/test_BioData_z.score.R

In stela2502/BioData: The package allows to annotate a numeric data.table with col and row data

#library(BioData)

set.seed(1)

rownames(dat) <- paste( 'gene', 1:100)
samples <- data.frame(SampleID = 1:10, sname = colnames(dat) )
annotation <- data.frame( GeneID = paste( 'gene', 1:100), Start= 101:200 )

x <- BioData$new( cbind(annotation,dat), Samples=samples, name="testObject",namecol='sname', outpath = "" )
expect_equal( class( x ), c('BioData', 'R6') )

z.score(x)

expect_true( length( which( round(apply(x$zscored,1,sd),digits=10) != 1 )) == 0 ,"all sd's == 1" )
