I am trying to reduce distance between + and * in TGFB2 in olive oil. No matter what distance I put the result is the same, even putting the same value hjust = -12.5 in both + and *. Mofiying the vjust to 0 and adjust the hvalue doesn’t seem to work either.
Not sure if there is an alternative
I already tried the alternative of label = “+ *” but this option doesn’t print any character.

p2 <-p2 + geom_text(    data = subset(df_plot2, gen == "TGFB2" & grup_int == "1"),aes(label = "+"), x = 1, y = "TGFB2",      vjust = 0, hjust = -14.5, size = 5) +   geom_text(data = subset(df_plot2, gen == "TGFB2" & grup_int == "1"),aes(label = "*"), x = 1, y = "TGFB2",      vjust = 0, hjust = -14.5, size = 5) +   geom_text(data = subset(df_plot2, gen == "TGFB2" & grup_int == "2"), aes(label = "+"), x = 1, y = "TGFB2", vjust = 0, hjust = -10, size = 5)
