Dear users,
I'm trying to get a dot plot but always end up with a boxplot. Can
someone please tell me what I am doing wrong?
df <- structure(list(FACETTE = structure(c(1L, 1L, 1L, 1L, 2L, 2L,
+ 2L, 2L), .Label = c("base", "tip"), class =
"factor"), Sq = c(274836,
+ 0.74182, 0.709205, 0.984552, 279869, 255712, 26566, 301464)), .Names =
c("FACETTE",
+ "Sq"), class = "data.frame", row.names = c(1L, 2L, 3L, 4L,
6L,
+ 7L, 8L, 9L))
with(df, plot(Sq~FACETTE, type="p"))
with(df, plot(Sq~FACETTE, type="n"))
I get boxplots in both cases. What should I do to get points instead of
boxes?
Thanks in advance for your help,
Ivan
