Hello all!
I have a problem to draw a polygon with R. My data is like this>
Year Nb.series Perc.pos Perc.neg Nature RGV_mean RGV_sd neg poz
1 1901 1 0.00 0.00 0 4.29 NA 0.00 0.00
2 1902 1 100.00 0.00 1 16.47 NA 0.00 100.00
3 1903 1 100.00 0.00 1 31.31 NA 0.00 100.00
4 1904 1 0.00 0.00 0 -9.62 NA 0.00 0.00
5 1905 1 0.00 100.00 -1 -22.55 NA -100.00 0.00

I try this code:
plot(seriep$Year,seriep$poz, type="l",ylim=c(-100,100))
lines(seriep$Year,seriep$neg, type="l",col="red")
polygon(c(seriep$Year,rev(seriep$Year)),c(seriep$neg,rev(seriep$poz),col="grey93",border=NA))
and this is the error>Error in xy.coords(x, y) : 'x' and 'y' lengths differ.
Please help me to solve this problem.
Thank you!
Best regards,
