1. Data in Geological Engineering

1.1 Aerial view of samples locations (download)

Plot an aerial view map (X, Y coordinates) of samples locations and optionally add a boundary polygon.

Variables to customize:

- varcolX <- 1 # index of the GTD frame X coordinate
- varcolY <- 2 # index of the GTD frame Y coordinate
- addpolygon=TRUE # option (TRUE or FALSE) to add a polygon
- titleGRAPH # global title of the plot

1.2 Aerial view of samples locations for Qualitative Variables (download)

Plot an aerial view map (X, Y coordinates) of samples locations with symbol colours of a qualitative variable.

Variables to customize:

- varcolX <- 1 # index of the GTD frame X coordinate
- varcolY <- 2 # index of the GTD frame Y coordinate
- varlistindex <- 4 # index of the GTD frame Qualitative Variable
- circlesize <- 3 # size of the circle symbol
- titleGRAPH <- "Representação em planta das amostras de solos" # global title of the plot
- colours <- c("yellow", "red", "green", "blue", "black") # colours of each qualitative value

3.3 Aerial view of samples locations for Quantitative Variables (download)

Plot an aerial view map (X, Y coordinates) of samples locations with symbol colours of intervals of a quantitative variable.

Variables to customize:

- varcolX <- 1 # index of the GTD frame X coordinate
- varcolY <- 2 # index of the GTD frame Y coordinate
- varlistindex <- 4 # index of the GTD frame Quantitative Variable
- circlesize <- c(1,5) # min and max size of the circle symbol
- titleGRAPH <- "Representação em planta das amostras de solos" # global title of the plot
- colours <- c("blue", "green", "yellow", "red") # colours of a ramp scale
