Description Usage Arguments Details Value Examples

The function obtain a symbolic polygonal variables from data of class 'paggregated', i.e aggregated data. For this, the researcher need to select the number of vertices.

1 | ```
psymbolic(pdata, vertices)
``` |

`pdata` |
an object of the class 'paggregated' that represents the representation of symbolic polygonal data. |

`vertices` |
the number of vertices for the polygon. |

psymbolic converts data represented by center and radius representation in symbolic polygonal data. It is importat that the researcher considers a positive number for radius. Besides, the variable vertices should be greater than 2 for the number of vertices.

When the object of class 'paggregated' is composed by a vector for center and one vector for radius a simple symbolic variable is obtained.

psdata is an object of class 'polygonal-variables', i.e. an environment, where for each object in the environment is a list with the polygons(matrix with dimention l times 2, where l represents the number of vertices).

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 | ```
## Obtaining a simple symbolic polygonal variable
cat1 <- as.factor(sample(1:20, 1000, replace = TRUE))
cv1 <- runif(1000) #classical variable
cvc1 <- data.frame(category = cat1, variable = cv1)
pol1 <- paggreg(cvc1)
out <- psymbolic(pol1, 6) #Hexagon
out$X1
## Obtaining three (or more) symbolic polygonal variables
cat2 <- as.factor(sample(1:20, 1000, replace = TRUE))
cv2 <- matrix(runif(3000), ncol = 3) #classical variable
cvc2 <- data.frame(category = cat2, cv2)
pol2 <- paggreg(cvc2)
out2 <- psymbolic(pol2, 8) #Octagon
out2$X1
out2$X2
out2$X3
