Axis value as percentage
Hello, I am using ggplot2 to display some distributions, I my data, there are percentages represented as 0.10, 0.13, ... I now want to do the axis show "5%", "10%", "15%", ... Is there is simple way to do this? I tried to use scale_y_prob(), but I didn't get through it. Thanks and regards, Christoph

Specify plot size
Hello, I have another (possibly easy) question: How to specify the size of a plot? When I draw a plot, I can freely change the size of the window, which is nice for single plots to find the best height/width ratio, but as I need a lot of plots in my work, I want to look them all the same, so I need to specify the size in advance. Thanks for help, Christoph

ggplot2 and Date class
I'm trying to plot a time series in ggplot, but a date column in my data frame is causing errors. Rather than provide my own data, I'll just refer to the scale_date example at: http://had.co.nz/ggplot2/scale_date.html , which reproduces the error. > df <- data.frame( date = seq(Sys.Date(), len=100, by="1 day")[sample(100, 50)], price = runif(50) ) > dt <- qplot(date,

jpeg() creating empty files with qplot() in a loop
Hello all, I'm stuck with a strange issue with writing jpegs of plots to a folder in a loop. This works: for (step in 1:length(steps)) { jpeg(filename=paste("frame_",sprintf("%05d",step),".jpg",sep="")) plot(steps[[step]]) dev.off() } But if I use qplot to generate the plot (which is my aim): for (step in 1:length(steps)) {

Unable to run smoother in qplot() or ggplot() - complains about knots
I get the following error when I run qplot() qplot(grade, read,data = hhm.long.m, geom = c("point", "smooth")) Error in smooth.construct.cr.smooth.spec(object, data, knots) : x has insufficient unique values to support 10 knots: reduce k. I am not sure how to tackle this problem. When I take a subsample (< 1000) than I am able to run that function but with my sample

ggplot, qplot: alpha channel for colors corresponding to factor
Hi, I have a qplot like the one in the minimal example below, except I also have faceting like this: qplot(jitter(Goodall),jitter(Better.adapt),colour=Second.adapt,facets=~Pol,data=d1) and with the real data I get quite a lot of overplotting, so I would like to add an alpha channel. In addition, I would like to be able to control which colors are used for each value of Second.adapt (which

qplot (ggplot2) faceting histogram with missing values
Hi, I've run into a difficulty with qplot function (in the ggplot2 package). I can facet histograms even when the faceting variable contains missing values, but only so long as the faceting variable is not a factor. Example: y1 <- rnorm(10) x1 <- c(rep(1,5), rep(2,4), NA) x2 <- factor(c(rep(1,5), rep(2,4), NA)) library(ggplot2) qplot(y1, geom = "histogram", facets =

qplot of ggplot package how to plot different size according to the values and not to the weights?
I have the following Data structure $ step45 : Factor w/ 2 levels $ obserror : num 6.2 6.2 5.6 6.6 6.6 ... $ Mon : num 2.2 2.0 1.0 3.2 2.0 ... $ inc.comp : num 4 5 2 5 5 5 5 5 4 4 ... all I wanted to do is plotting Mon against obserror, the colors should be by step45 and the size of the symbol should be according to inc.comp so I did this:

Strange error in qplot
Hi all, whenever I try to plot a histogram using qplot() function of "ggplot2" library, I get error like this : > qplot(rnorm(1000), geom="histogram", binwidth=0.2, main = "", xlab="", > ylab="") Error in scale[[1]] : subscript out of bounds However if I remove ylab="" argument, then it is working fine. Am I missing something?

ggplot2 qplot pch not working anymore
Is there a way to use a continuous variable to pch in qplot? I believe this worked in previous version. I need to specify certain values of a shape for particular points so that multiple graphs all show the same shapes for the same streams. I have gone to the original data and added a pch column that I would like to use to specify the shapes to pch in qplot. Any help would be greatly

Problems with boxplot in ggplot2:qplot
Dataframe closed contains balances of closed accounts: each row has month of closure (Date-type column month) and latest balance. I would like to plot by-month distributions of balances. A qplot call below produces several warnings and no output. Can anyone help? Thank you. PS. A really basic task, very similar to the examples on p. 71 of the ggplot2 book, apart from a Date grouping column; I

change order of plot panels in faceted ggplot/qplot
Hi, I have a 5-paneled figure that i made using the facet function in qplot (ggplot). I've managed to arrange the panels into two rows/ three columns, but for the sake of easy visual comparisons between panels in my particular dataset, I want to have the two plots on the bottom align on the right hand side of the figure instead of the left. Here's an example: m <-

Changing histogram stack in qplot

qplot and for loops
I have 4 columns and 56 rows of made up data that I want to plot as a series of bar graphs. The idea is to create one bar graph for each of the 4 columns using a for loop. I tried the following command in RStudio and when I type x in the console I get just the 4th graph instead of all four graphs. I did not define what x is before hand. I was not sure what it would be.

specifying plot symbol sizes in qplot or ggplot2
Hi. first things first ... thanks for ggplot2. Now my question. I'm using qplot to generate a plot as follows where X,Y,Z, A are columns in a dataframe. qplot(X, Y, data=XYDATA, color=Z, geom=c("point"), size=A) This works as expected. Factor A has three levels so there are three sizes of the point plot symbol. I understand that the factor levels are mapped to symbol sizes.

Currently showing as red and blue, but need it to be black and white for publication. Any suggestions please? Using a data set June, which is str:
