[R] Multiple XY Lines Plot

Hi list, I’m trying to plot lines in the same graphic. There are lots of similar topic on the list history. I’ve read about xyplot (lattice) and other ways to do that but I only got complex error messages, and wasn’t able even to start a decent R scrip. Well I have some paired information (each H W

[R] Retrieving x argument name from a trellis object in R 2.8.0

[R] Reading tables using a truncated name

Dear all, I am trying to read a bunch of csv files using read.table() that are named "test_xx.csv" where "xx" has no particular pattern. Is there a way of reading all the files by specifying a truncated file name e.g. "test_" with some wild card characters, or would I have to laboriously c

Re: [R] Manipulation in timeSeries object:how to use the function "applySeries" by daily?

Take a look at xts, a time series class that extends zoo and is compatible (forward and backwards) with all major time-series classes, including timeSeries from Rmetrics. It has a few functions that may be of interest: ?endpoints ?period.apply It may also be useful to use the Fortran-based aggr

[R] Plot matrix

Hi, I would like to plot the rows of a matrix. Is there a better way as doing it in the following way?: plot(matrix[1,], type="l") for (i in 2:dim(matrix)[1]) { lines(matrix[i,], type="l") } Cheers -- View this message in context: http://www.nabble.com/Plot-matrix-tp20438584p20438584.
