Recently I download a file with Indian data quality data in Kaggle (https://www.kaggle.com/venkatramakrishnan/india-water-quality-data). I decided to explore data visualization package to learn how to make neat and tidy visualization using heat maps.File has the following structure: water.quality<-readRDS("water.quality.rds") head(water.quality) ## State.Name District.Name Block.Name Panchayat.Name ## 1 ANDHRA PRADESH EAST GODAVARI(04) PRATHIPADU(10) GOKAVARAM(04) ## 2 ANDHRA PRADESH
