![]() ![]() The table rows correspond to 169 meteorological stations. Each table column represents a variable, with values of the same typeįor example, the file rainfall.csv, which we are going to work with later on (Section 4.4), contains a table with information about meteorological stations in Israel (Figure 4.1).Each table row represents an observation, with values possibly of a different type for each variable.The convention, in R and elsewhere, is that: A ame is basically a collection of vectors comprising columns, all of the same length, but possibly of different types. 12.2 Inverse Distance Weighted interpolationĪ table in R is represented using the ame class.11.3 Aggregation of spatio-temporal rasters.10.7.5 Extracting to polygons: multi-band.10.7.4 Extracting to polygons: single-band.10.7.3 Extracting to points: multi-band.10.7.2 Extracting to points: single-band.8 Geometric operations with vector layers.6.6 Generalizing raster algebra with st_apply.6.4.3 True color and false color images.6.4.1 Arithmetic and logical operations on layers.6.2.1 Selecting rows, column and layers.5.3.7 Visualization with plot, mapview and cubeview.4.4.3 Example: the rainfall.csv dataset.3.3.2 Function definition vs. function call. ![]()
