# Dear all,
# Thank you for taking your time.
# What I would like to do:
# (Run the code below to see what I am referring to)
# I want lines connecting the medians of of the boxes. I do not want a
function, just a simple,
# straight connection between points. I also would like the lines to be
different: lty=c(1:3)
# Furthermore, I wish to change the line/dot marking the medians to be
pch=c(1:3). It seems not to be so simple when using facet_wrap? I have
obviously missed something obvious.
# Finally, I would like the boxes to be filled white and to have the legend
reflecting this.
# I know that this was many questions, I apologize if some may seem basic. It
is just that I am
# "jumping packages" the whole time and sometimes par() adjustments work and
sometimes not.
# I have searched alot for answers, but as a ggplot2 beginner, I have failed to
find a solution
# to my problems above.
# I would like to thank the programmers for a great package. The layer
principle is much easier to work with.

# Some dummy data:
mydata<- data.frame(week = factor(rep(c("19", "21", "23", "25", "27", "29",
"31", "33",
"35", "37", "39"), each = 45*3)),
#week
station = factor(rep(c("BY31", "B1", "H2", "H3", "H4",
"H5", "H6", "H7", "H8"), each =
15)), #station
organism = factor(rep(c("zpl", "ses", "cy"), each = 5)),
#organism
var1 = rnorm(1485, mean = rep(c(0, 3, 15), each = 40),
sd = rep(c(1, 3, 6), each = 20)))
p <- ggplot(mydata, aes(x = week, y = var1, fill = organism)) +
geom_boxplot() +
facet_wrap(~ station, ncol = 3) +
theme_bw() +
theme(strip.background = element_blank())+
ylab("var1")+
xlab("week") +
geom_smooth(aes(group = 1), method="lm", se = F) + #Here is my problem.
theme(strip.text.x = element_text(size = 12, colour="black", family="serif",
angle=00)) +
theme(axis.text.x = element_text(size = 12, colour="black", family="serif",
angle=90)) +
theme(axis.text.y = element_text(size = 12, colour="black", family="serif",
angle=00)) +
geom_hline(yintercept=0, linetype=3) #draws dotted line at 0
p
# method="lm" is definately wrong,
# I just added it to be a ble to draw some lines at all.
# I also suspect geom_smooth to be wrong.
### TO CLARIFY: I want the medians connected within each level. cy medians
connected and
# and ses medians connected and zpl connected. Not cy-ses-zpl, but that is
perhaps obvious.
### Thank you for your time!
# with kind regards
