-

how can modify below code bring title top right corner.

value <- c(0, 1, 20, 3, 3, 0, 0, 5, 2, 5, 2, 7)     names.arg =c("0-15","15-19","20-24","25-29","30-34",                  "35-39","40-44","45- 49","50-54","55-59","60-64","65 jahre oder Älter")     df <- data.frame(names.arg = names.arg, value = value)      p1 <- ggplot(df, aes(x=names.arg, y=value)) + geom_bar(stat = "identity")     save(p1, file = "p1.png")      value2 <- c(0, 1, 20, 3, 3, 0, 0, 5, 2, 5, 2, 7)     names2 =c("0-15","15-19","20-24","25-29","30-34",                  "35-39","40-44","45- 49","50-54","55-59","60-64","65 jahre oder Älter")     df2 <- data.frame(names = names2, value = value2)      p2 <- ggplot(df2, aes(x=names, y=value)) + geom_bar(stat = "identity", fill = "red")    title <- textgrob("graph 1.2: plot", gp = gpar(fontsize=13,font=4))    grid.arrange(p1,p2,nrow=2,top = title)

reference "error in grid.arrage - arrangegrob() function"

instead of gridextra use package cowplot:

#create grid pgrid <- plot_grid(p1, p2, nrow=2)  #create title title <- ggdraw() + draw_label("graph 1.2: plot", hjust=-5, fontface=4, size=13)     #combine plots , title plot_grid(title, pgrid, ncol=1, rel_heights=c(0.1, 1))
