how can I change the "key" of the caption below, so that it stays in the horizontal position, without changing the vertical lines of the chart. Also, how to leave the caption background with the same color as the first layer (or "layer") of the chart?
set.seed(000)
m <- matrix(rnorm(100,0,1),100,1)
dt <- data.frame(m)
names(dt) <- c("X")
g2 <- ggplot(dt, aes(x=X))
g2 <- g2+geom_histogram(aes(y=..density..), # Histogram with density instead of count on y-axis
binwidth=.5,
colour="black", fill="white",breaks=seq(-2, 2, by = 0.1))
g2 <- g2+geom_density(alpha=.3, fill="#cccccc") # Overlay with transparent density plot
g2 <- g2+ geom_vline(aes(xintercept=0, linetype="Valor Verdadeiro"),show.legend =TRUE)
g2 <- g2+ geom_vline(aes(xintercept=mean(dt$X, na.rm=T), linetype="Valor Estimado"),show.legend =TRUE)
g2 <- g2+ scale_linetype_manual(values=c("dotdash","solid")) # Overlay with transparent density plot
g2 <- g2+ xlab(expression(paste(gamma[1])))+ylab("Densidade")
g2 <- g2+ theme(legend.key.height = unit(2, "cm") ,
legend.position = c(0.95, 0.95),
legend.justification = c("right", "top"),
legend.box.just = "right",
legend.margin = margin(6, 6, 6, 6),
legend.title=element_blank(),
legend.direction = "vertical",
legend.background = element_rect(fill="gray", size=.5, linetype="dotted"))
g2 <- g2+ guides(linetype = guide_legend(override.aes = list(size = 1)))
g2
Actually, I want to rotate is not the whole caption, but the "Key" of it. On this page (http://moderngraphics11.pbworks.com/f/ggplot2-Book09hWickham.pdf) book you can see what is "key".

I want to rotate the line inside the legend that is in the format
dotdash
andsolid

@fsbmat understood, the more work, I will only have time to research later
