Dear all,

I am looking for a way to generate different plots in base R with adding points and lines manually to the plot. Here is my sample data:

Is it possible to add points() to a plot with the values from the first row (STARTING POINT X_START_YEAR/Y_START VALUE to END POINT: X_END_YEAR/Y_END_VALUE) and then plot again in the same plot in the same scheme the values for the second row.

After this plot has been generated a new group defined by NAME starts and a new plot should be generated for rows 3 and 4 in the same scheme as above.

The goal in the end is to connect the points by a line using type=l.

Unlike in this sample data, I have about 40000 rows and 1300 groups in the end and I am looking for a way to correctly plot this data in base R. Any help is appreciated!

Kind regards,

```
xy <- data.frame(NAME=c("NAME1","NAME1","NAME2","NAME2"), X_START_YEAR=c(1984,1986,1899,1903), Y_START_VALUE=c(75,25,-90,-8),X_END_YEAR=c(1986,1994,1909,1924),Y_END_VALUE=c(20,50,-15,-70))
xy
NAME X_START_YEAR Y_START_VALUE X_END_YEAR Y_END_VALUE
1 NAME1 1984 75 1986 20
2 NAME1 1986 25 1994 50
3 NAME2 1899 -90 1909 -15
4 NAME2 1903 -8 1924 -70
