I'm making a big plot to compare forecast-models. But how can one add additional text to a label? For example this is one of the plots that I need additional text beside the y-label.
(qplot(y = VaR90_n_roll1, x = 507:1006, geom = 'line')
+ geom_line(color = 'green')
+ geom_point(aes(x = 507:1006, y = sp500_logreturns[507:1006]))
+ coord_cartesian(ylim = c(-0.065,0.05))
+ labs(y = c('Log returns',
'Model 1'), x = '')
+ ggtitle("")
+ theme(plot.title = element_text(hjust = 0.5)))
