Description: Data analysis and visualization is an integral part of scientific discovery. Boasting a vast collection of open-source (free) libraries for diverse data operations, visualization and statistical analyses, R has become a sought-after skill for researchers, data analysts and researchers alike. This two-part workshop will provide hands-on exercises on data visualization using R. In Part-I, we will discuss plotting basics, data manipulation, ggplot. Introduction to spatial data mapping and interactive plots using leaflets will be explored. In Part-II, we will demonstrate geospatial operations like projections, resampling, spatial extraction, cropping, masking etc. using rasters, shapefiles, and spatial data frames. Conversion from/to different data formats like data frames, matrices, rasters, and structured data like NetCDF will also be discussed. Advanced topics will include working with data cubes (raster stack/ brick), layer-wise operations on data cubes, cell-wise operations on raster time series by implementing user-defined functions.
