Dear Anna,
Is this what you would like?
Summ <- ddply(mydata, .(factor3,factor1), summarize,
mean = mean(var1, na.rm = FALSE),
sdv = sd(var1, na.rm = FALSE),
se = 1.96*(sd(var1, na.rm=FALSE)/sqrt(length(var1))))
Summ$Grouping <- c("AB", "AB", "CD", "CD", "EF", "EF")[Summ$factor1]
Summ$factor1bis <- c("0", "1", "0", "1", "0", "1")[Summ$factor1]
ggplot(Summ, aes(factor3, mean, group = factor1bis, shape = factor1bis, linetype = factor1bis, ymin = mean - sdv , ymax = mean + sdv)) +
geom_point(position = position_dodge(width = 0.25), size = 3) +
geom_line(position = position_dodge(width = 0.25)) +
geom_errorbar(width = 0.3, position = position_dodge(width = 0.25), size = 0.3) +
facet_wrap(~Grouping, ncol = 2) +
theme_bw() +
ylab(expression(paste("my measured stuff"))) +
xlab("factor3") +
labs(shape = "factor1", group = "factor1", linetype = "factor1")

To call in the statistician after the experiment is done may be no more than asking him to perform a post-mortem examination: he may be able to say what the experiment died of.

The combination of some data and an aching desire for an answer does not ensure that a reasonable answer can be extracted from a given body of data.

Onderwerp: [R] Ggplot2: Moving legend, change fill and removal of space between plots when using grid.arrange() possible use of facet_grid?
Hi,
# For publications, I am not allowed to repeat the axes. I have tried to
remove the axes using:
# yaxt="n", but it did not work. I have not understood how to do this in
ggplot2. Can you help me?
# I also do not want loads of space between the graphs (see below script
with Dummy Data).
# If I could make it look like the examples on the (nice) examples page:
# http://www.ling.upenn.edu/~joseff/rstudy/summer2010_ggplot2_intro.html
# using the facet_grid(), I would be very very happy.
# I also do not want the gemoetric points to be filled and the fill="white"
commande
# does not seem to work - why? and are there alternatives?
#Furthermore, I would like to add legends to inside the plot area instead of
on the side. Like when you use plotrix() and brkdn.plot:
legend("topright", c("A", "B"), pch=c(0,1), bg="white",
lty = 1:2, cex=1, bty="n")
# This did not work in ggplot2. What are my alternatives. I have extensively
searched the internet and have I missed something obvious, it was due to
# tiredness and not to lazyness.
# Some dummy data:
mydata<- data.frame(factor1 = factor(rep(LETTERS[1:6], each = 80)),
factor2 = factor(rep(c(1:5), each = 16)),
factor3 = factor(rep(c(1:4), each = 4)),
var1 = rnorm(120, mean = rep(c(0, 3, 5), each = 40),
sd = rep(c(1, 2, 3), each = 20)),
var2 = rnorm(120, mean = rep(c(6, 7, 8), each = 40),
sd = rep(c(1, 2, 3), each = 20)))
# Splitting data into 3 data frames (based on factor1)
# If I could do this using for example facet_wrap() or facet_grid(), I would
be very
# happy! I have tried but failed that method.
