...n var2 with a variable whose value is "var2" (e.g. dat[,col2] <- dat$var1, where col2 = "var2"). It is easier and more clear to use the [] operator to reference a data frame column with a variable, rather than using the $ operator with the parse() function.

...s an easier way. My way is: M <- matrix(ncol=ncol(df) , nrow=nrow(df) , as.numeric(as.matrix(df))) where 'df' is the data frame. I am wondering if there is a function, similar to as.numeric(), that converts each column of the matrix 'as.matrix(df)' to numeric.

Hi all, I have a 16 bit image (TIFF) and i want to analyse the pixels distribution. So, i obtain a matrix which values are between 0 and 2^16 -1. Now i would like to represnt this image with the fucntions rgb() and image(). I am not sure , but i think that only 256 colors are available. So is there a solution to represent all the palette of the colors or i have to limit the representations with

Hi all, I was wondering whether it is possible to change the angle of all axis in a scatterplot3d graph. I know that there is one parameter <angle> but I was wondering whether it is possible to control the angle of all different axis individually (eg by using <anglex><angley><anglez>). In addition I was wondering whether there is a way to change the angle of a plot

Hello, Is there an option I can easily set to put labels next to the points in a simple plot? The closest I got to it was to use the option pch, but this replaces the point symbol with the character specified, and it is not what I want.

Hello again, First I want to thank all the people who answered my question about line width in graphs. I promise I will learn the 'par' help page by heart for the end of the month ! I now want to trace some ellipses to emphasize groups of data. I found how to trace circles with 'symbols()', but no ellipse. I'm planning on writing my own function based on

Dear R-guRus: I have a problem with the format of my data in R. Let's say I have a HUGE text table which consists of columns of numerical data, separated by tabs, but in some places rows of text (error messages, etc) are inserted in between rows of numerical data. Because the data file is so huge and because I have thousands of these files, it's unpractical to try and go thru these

Hello, I have developed a R package. When I pass it through the rcmd check command (windows 98) to see if it is ok, everything works fine until there is a call to the program "sh.exe". It seems that rcmd calls it with the option --c, but it doesn't seem to be a legal option. After that, when rcmd tries to create a directory inside the "package_name.Rcheck" directory there

Hello, This is perhaps more of a regression question than R, but I am learning both, so would appreciate your wisdom here. I have some data which reflects power load for an electrical generating system, with some temporal features. The data fields look like this: D,MON,DAY,YR,HR,WDAY,DRYBULB,WETBULB,LOAD 4455 5 13 92 13 4 70 63 1617 4456 3 9 92 13 2 73

I am testing out the grid-plots, but get into a problem making a legend. I have a line plot and some points, following the model in grid.plot.and.legend() i manage to get the points correctly in the legend, but what do I do with the line? (Of cource, I can just draw a line at the right location on the plot, but I would prefer to use legend) Morten -- Morten Sickel Norwegian Radiation

Is there a way to call Matlab and Gauss code in R? I see functions that work for C/FORTRAN, but not for other languages.
