Hi everyone. I'm trying to use small letter phi in a graph produced in R. However, the small letter phi does not look as it should. In fact, it looks like this: http://r.789695.n4.nabble.com/file/n3963311/Untitled.png instead of what is here http://en.wikipedia.org/wiki/Phi Here's the code I use: expression(phi [1]) Anyone has an idea?

Hi everyone. Is it possible in R to create a matrix or a list (vector) or R object. For instance, I have f1 <- function(x) sqrt(x%*%x); f2 <- function(x) (2x+1); I would like to do something like L <- List(); L[1] = f1; L[2] = f2; So, is there a way to create matrix or vector that can contains R object.

Hi everyone. I have a quick question regarding the look of my legend in my plot. As you can see in the next figure, I have 3 series. http://r.789695.n4.nabble.com/file/n3067466/legend.png However, I find rather difficult to differentiate the series 1 and 3 according to their line type (lty). I would like to know if it was possible to make the line type in the legend to appear more clearly.

Hi everyone. I would like to know if it was possible to insert a plot into another one. For example I have a plot and I would like to add a smaller plot in the top right corner.

Dear R users. In a loop, I set the title of my graph with : mytitle = expression(paste(delta^13,'C Station ', i) title(mytitle) However, instead of using value of i, it will literally use "i" character. Any one know the way to concatenate the value of i to the mathematical expression? With regards, Phil -- View this message in context:

Hi everyone. I have a long label that I would like to split. I found that I could use "strwrap" for simple text. However, this is not working with this label: str = expression(paste("< 20 ?m phytoplankton ","(cells ? ",mL^-1,")")) plot(...., ylab = strwrap(str,20),...) I suspect this is because I'm using "expression" for form my label.

Hi everyone. I would like to modify the axis on my plot. First, I would like to make a plot without the box. so I use : plot(x,y, axes = FALSE, type = 'l') Then, I call : axis(1, tck = -0.02) axis(2, tck = -0.02) to have X and Y axis appear. However, I would like them to join at the origin instead of having a space between the 2 axis. I can't find the parameter to modify to get

Dear R users. I'm currently making a report with knitr (RStudio) where I would like to plot a googleVis map. However, the map generated is an HTML file which I don't know how to integrate it in my report. So my question is how to include a map generated with googleVis in a PDF created with knitr/sweave.

Hi everyone. I have a vector like this: x = c(1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,2,2,2,2,2,2,2,2,3,3,3,3,3,3,3,3,2,2,2,2,2,2,2,2) I would like to associate a colour to each of these entry. For example, I could use /topo.colors(3)/ (since I have 3 groups). I know it is easy to do this with /if/else/ statements, but I would like to find a proper way to do this. Thanks in advance, Phil -- View

Hi everyone. Based on a dependent variable (y), I'm trying to generate some independent variables with a specified correlation. For this there's no problems. However, I would like that have all my "regressors" to be orthogonal (i.e. no correlation among them. For example, y = x1 + x2 + x3 where the correlation between y x1 = 0.7, x2 = 0.4 and x3 = 0.8. However, x1, x2 and x3

Hi everyone. I have these data : myData = data.frame(Name = c('a', 'a', 'b', 'b'), length = c(1,2,3,4), type = c('x','x','y','z')) which gives me: Name length type 1 a 1 x 2 a 2 x 3 b 3 y 4 b 4 z I would group (mean) this DF using 'Name' as grouping factor. However, I have a

Hi all. I'm ploting a raster and I can't find the proper way to move the legend. For example, r = raster(system.file("external/test.grd", package="raster"))plot(r) How can I put the legend at the desired position? Thank in advance,Phil [[alternative HTML version deleted]]

Hi everyone. I would like to make a graphic with 2 subplots (lets say A and B). For instance, I use : par(mfcol = c(2,1)); The 2 subplots use the same X axis. So I provide no tics labels and no xlab for the top plot. I would like the second plot to be right bellow the first one (small margin). So my question is how I can keep a small gap between the 2 plots while having enough space under

Hi everyone. I'm using this following code: pdf(file="Fig5.pdf", width = 4.86, height = 6.29, pointsize = 10, family ='Times') par(mfcol = c(3,2), mai = c(0.4,0.8,0,0), omi = c(0.7, 0, 0.7, 0.1)); hist( rnorm(100) ) dev.off() When I open this in any vectorial software (like Illustrator), it says that my font size is 7 instead of 10 that I specified. I have tried

Hi everyone. I'm trying to display the r^2 of a linear regression on a plot using text(...). I first build the string to display. However, I can't find why this is not working (it display literally r^2 instead of r superscript 2). r2string = expression(paste(r^2)," = ", r2); Any help would be greatly appreciated, Phil -- View this message in context:

Hi all. I have been trying to plot 9 bubble plots on each page of a PDF file. For this, I'm using : par(mfcol = c(3,3), mar = c(3,3,3,3), oma = c(0,0,0,0)); However, when plotting the bubble plot (gstats package), it plots the graph on a full page. I tried to plot something else with plot(x,y) and it works as intended. So I'm guessing the problem comes from the bubble plot itself.

Hi everyone. I'm trying to do a loess with missing value on independant variable. doc = c(2.27904, 2.59536, 7.44696, NA, 6.24264, 4.58400, 5.79192, 5.39502, 7.41216, 4.09440, 4.22868, 4.24620, 5.43804, 1.95528); distance = c(26.5,56.5, 90.3, 123.0, 147.5, 176.0, 215.7, 229.3, 252.0, 325.3, 362.0, 419.3, 454.6, 470.0); myloess = loess(doc ~ distance, na.action = na.omit); plot(distance,

Hi everyone. I'm using matrix product such as : #Generate some data NCols = 5 NRows = 5 A = matrix(runif(NCols*NRows), ncol=NCols) B = matrix(runif(NCols*NRows), ncol=NCols) #First calculation R = A%*%B for(i in 1:100) { R = R%*%B } I would like to know if it was possible to avoid the loop by using something like mapply or anything else.

Hi everyone. I have a linear regression where I retrieve the R2 like this: r2 = sprintf('%4.2f %s',(summary(reg1)$r.squared)) In my figure I have a legend where I would like to add that R2 value to the legend text. Something like: My text R^2 = r2 legend('topright', inset = .05, title='light ratios', pch = c(21), c(paste('Green/Red', R^2, '=', r2)),

Hi everyone. I have an histogram like this one: http://imageshack.us/photo/my-images/442/dfsdfsdj.jpg/ I would like to remove the extra space under the histogram so it "touch" the x axis.
