Radar data on the inside

Let’s have a look on our data file!

x
dim(x)
str(x)
slotNames(x)
A <- x[90:200, 5:10]

What is the minimum, maximum or mean value of a specific column or row? Getting information on the values and range of a certain data point or object can be helpful to identify problems.

min()
max()
mean()

During processing radar data set is sometime necessary to enhance the data set. It can be either for visualization or adjusting mishaps from the survey, e.g. line collected in two pieces.
