In this video i have demonstrated how to define your won theme using theme elements you defined for your best customized plot.
Its really easy. you just have to specify a function with theme name you want and in curly bracket of function just cut paste the theme elements from your best customized plot.
Now just as any predefined theme add this theme to your customized plot.
#code
library(ggplot2)
str(ToothGrowth)
ToothGrowth$dose = factor(ToothGrowth$dose)
apa theme
theme_apa = function(){
theme_classic()+
theme(
legend.background = element_rect(color="black"),
plot.title=element_text(family = "serif",size=14,face="bold"),
plot.subtitle=element_text(family = "serif",size=14, face="italic"),
axis.title = element_text(family = "serif",size=12, face="bold"),
plot.caption =element_text(hjust=0))
}
ggplot(ToothGrowth,aes(dose, len, fill=supp))+
geom_bar(stat="summary", fun="mean", position="dodge", width=0.6, color="gray60")+
stat_summary(geom="errorbar", fun.data=mean_se,position = position_dodge(width=0.6), width=0.2)+
scale_y_continuous(expand=c(0,0))+
scale_fill_manual(values=c("yellow","skyblue"))+
