### Dataset preview
BJdata()

### Convert binary variables into factor type. 
BJlung$gender = factor(BJlung$gender)
BJlung$heat = factor(BJlung$heat)
BJlung$cigwear = factor(BJlung$cigwear)

### Merge miRNA and lung function dataset.
BJdata <- merge(BJmirna, BJlung, by=c("SID","WD"))

### Sort the data by study subject id and multiple measurement indicator.
BJdata <- BJdata[with(BJdata, order(SID, WD)), ]
