GGPLOT2: Distance of discrete values of from each end of x-axis
Hi Group,
I have been working with the code below. Everything seems to work
okay, except that the discrete values on the x-axis are far from each
end of the graph. I've tried several things including changing the
discrete values and playing with the limits, but can't get it to work.
I tested this on simulated data and do not have the same problem, so I
guessing it is how I'm

Problem plotting continuous and discrete series in ggplot with facet
I have data that plots over time with four different variables. I would
like to combine them in one plot using facet_grid, where each variable gets
its own sub-plot. The following code resembles my data

require(reshape2)
subm <- melt(economics, id='date', c('psavert','uempmed','unemploy'))

ggplot- using geom_point and geom_line at the same time
Hi
I am plotting line chart using ggplot and want to use geom_line and
geom_point simultaneously.
I get the plot but now I have two legends. None of the legend is
representing the true values. I need the legend with shape and color both.
Thanks

Change default order of colors & line types
Dear R users,
I'd like to change the default order of colors & line types.
Especially I am using ggplot2 and using color Set1.
In Set1, the default color order is red, blue, green, violet,.. ect.
However, I want to put red in fourth (not first).
Likewise, I want to change the order of default linetype. I want to
put "solid" line in fourth.
How can I do thses?

dual y-axis for ggplot
Hi,
To my knowledge, an excellent of ggplot with a second y-axis is
https://rpubs.com/MarkusLoew/226759
In this example, the author uses two colors for the two lines, but the
line shapes are the same -- both are solid. Could each line have its own
color as well as its own shape? For example, can I make the red line with
the linetype "twodash", while the blue line with the

Problem building up ggplot graph in a loop.
Folks,
I want to automate some graphing using ggplot.
Here is my code
graphChargeOffs2<-function(coffs) {
ggplot(coffs, aes(levels))
dataNames<-names(coffs)[!names(coffs) == "levels"]
for(i in dataNames) {
thisData<-coffs[[i]]
last_plot() + geom_line(aes(y = thisData, colour = i))
}
last_plot() + ylab("Total Chargeoffs")
}
coffs is a data.frame.

barplot colors
Hi,
In barplot(height, col = ...), the col = vector recycles so that the
same colors are used for each bar. I would like to use different colors
in different bars (corresponding to another piece of information, here,
the region of the country being represented).
For example,
x = matrix(c(5,2,3,1),nrow=2)
barplot(x,col=1:4)
will draw two bars with two segments each, but each colored red and

dual y-axis for ggplot
Hi John,
You can try the following:
override.linetype=c("twodash","solid")
p <- ggplot(obs, aes(x = Timestamp))
p <- p + geom_line(aes(y = air_temp, colour = "Temperature", linetype
="Temperature"))
p <- p + geom_line(aes(y = rel_hum/5, colour = "Humidity",

ggplot: Trouble with xlim() and discrete scales
I'm learning ggplot and am a little confused. Sometimes discrete scales work
like I'd expect, and sometimes they don't. For example...
This works exactly like one would expect:
df<-data.frame(names=c("Bob","Mary","Joe","Bob","Bob"))
ggplot(df,aes(names))+geom_histogram()
But this yields an error:

xyplot, groups and colors
Dear ExpeRts,
I am trying to plot a bunch of growth curves and would like to get
some more control over groups and line colors than I seem to have.
Example:
# make some data
dat <- Orange
dat$group <- ifelse(dat$Tree%in%c('1','4','5'), 'A', 'B')
# plot
xyplot(circumference~age, dat, groups=group)
# now use lines to make the growth curve more

legend order in ggplot2
Hi,
I'd like to graph three lines on ggplot2 and I intend the lines to be
"solid", "dashed", and "dotted". The legend names are "name_b", "name_a",
"name_c". I'd like to legend to present in the order: the "name_b" at the
top, and "name_c" at the bottom.
As a consequence, the legend is indeed in the order:

difference between the two values, like this
