### Examples

    motif_folder= "extdata/pwm"
    motif_names = c("HepG2","MCF7","HUVEC","ProgFib")
    motifs = list()
    for (name in motif_names) {
      fileName = paste(motif_folder,"/",name,".pwm",sep="")
      file = system.file(fileName, package = "DiffLogo")
      motifs[[name]] = getPwmFromPwmFile(file)
    }

    pwm1 = motifs[[motif_names[[1]]]]
    pwm2 = motifs[[motif_names[[2]]]]

    diffLogoFromPwm(pwm1 = pwm1, pwm2 = pwm2, stackHeight = sumOfAbsICDifferences)
