ggplot2 font size and bold

Try:?theme(axis.title=element_text(face="bold",size="14",color="brown"),axis.text=element_text(size=14,face="bold")) 

A.K.


How can I increase the size and make bold of the items named under 
outcome in the example data set? I can make changes to label outcome, 
but not to individual components(alcohol, coffee etc.. ). ?Likewise, I 
?want to make similar changes in the vertical y axis numbers. 

ggplot(df2, aes(x = exp, y = pinc, ymin = lcinc, ymax = ucinc)) + 
? geom_linerange(position=position_dodge(width=0.70)) + geom_point( size = 4.5) ?+ 
? ylab("Percent Increase in Mortality") + ? geom_hline(aes(yintercept = 0)) + xlab("Outcome") + 
? theme(axis.title=element_text(face="bold",size="14", color="brown")) 



structure(list(pinc = c(0.456634704861525, -0.0917186505511203,
