    I have found the solution:

     

    library(maps)
library(geosphere)
library(magrittr)

Punto1 <- c(dataset$O.Lon,dataset$O.Lat)
Punto2 <- c(dataset$D.Lon,dataset$D.Lat)

map("world", xlim=c(-10,5),ylim=c(35,44) ,col="#1a2732", bg="white", fill=TRUE, lty = 0, interior = false,mar = c(0.1, 0.1, 0, 0.1))

points(x=dataset$O.Lon, y=dataset$O.Lat, col="#96ce00", cex=2, pch=20)
points(x=dataset$D.Lon, y=dataset$D.Lat, col="#96ce00", cex=2, pch=20)

inter <- gcIntermediate(Punto1, Punto2, n=50, addStartEnd=TRUE, breakAtDateLine=F)             
lines(inter, col="#96ce00", lwd=2)

    The easiest one :-)
