ggplot2 - How can I manipulate a ggplot in R to allow extra room on lhs for angle=45 long x-axis labels? -

- ggplot2 plot area margins? 1 answer
i have several geom_bar ggplots have long names x-axis text. if plot them @ angle=90, takes lot of room @ bottom of graph, trying angle=45. causes left hand side of first label cut off. there way increase left margin?
(not allowed post image example)
ggplot(aes(x = cm, y = ahead_aadt), data = sbt) + geom_point( ) + geom_line() + ggtitle("ahead aadt traffic counts on 101 in s santa barbara cty") + theme(axis.text.x = element_text(angle=45, size = 9, color = "black", face = "plain", vjust = 1, hjust = 1), panel.grid.major.x = element_line(colour = "black", linetype = "dotted")) + xlab("cumulative mileage") + ylab("ahead aadt") + scale_x_continuous(breaks = sbt$cm, labels = sbt$description)
this not best answer, added several "\n\n\n" before y-axis label text made label text wider. moves actual plot , associated labels farther right, giving more room text on left.
ggplot(aes(x = cm, y = ahead_aadt), data = sbt) + geom_point( ) + geom_line() + ggtitle("ahead aadt traffic counts on 101 in s santa barbara cty") + theme(axis.text.x = element_text(angle=45, size = 9, color = "black", face = "plain", vjust = 1, hjust = 1), panel.grid.major.x = element_line(colour = "black", linetype = "dotted")) + xlab("cumulative mileage") + ylab("\n\n\nahead aadt") + scale_x_continuous(breaks = sbt$cm, labels = sbt$description)
