Hi, I think I found the problem. It lies in my Fortran program. Is there a way, after a DO loop, to make sure it does NOT return anything?

Hi, Is it possible to add a subtitle that appears directly below the main title? I tried the "sub" parameter, but it adds sub-title to the bottom of the plot.

Hi, Suppose I have created something like this in R: foo <- "myfoo" and I want to find out the number of character in foo (in other words, R should return 5 since "myfoo" has 5 charactors. How can I do it? I tried: length(foo) but it returned 1. Cheers, Kevin ------------------------------------------------------------------------------ Ko-Kang Kevin Wang

Hi, Now suppose I have just one list called FOO, which has 25 objects, e.g.: [[1]] 1 2 3 4 5 [[2]] 6 7 8 9 10 . . . And I want to do something like: FRED <- data.frame(cbind(unlist(FOO[[1]]), unlist(FOO[[2]]), # ... for all 25 subsets )) Is it possible to do this, without doing unlist(FOO[[i]]) 25

Hi, Say I did something like: par(mfrow = c(1, 2)) plot(1:10) plot(1:10) and I'd like to have an overall title, i.e. a title that would appear, centered, on the top of both plots, rather than the top of the last plot. I tried: title("FOO", outer = T) but it doesn't appear right. Half of the FOO is outside the figure region and can't be seen... Is there another

Hi, Say I want to do something like fitting 10 different sized trees with rpart() function. The only modification I need to do is to set 10 different cp's, which I have in a vector called foo. Can I do something like: for(i in 1:10) { rpart(y ~ ., cp = foo[i], data = mydata) } My problem is, I wish to save the 10 rpart objects into 10 different names, my.rpart1 ~ my.rpart10, for

Hi, Suppose I have a function: myfunc <- function(x, y) { ... } And within the function I want to print out the name of the x, y vectors. For example, if I do: > myfunc(foo, goo) [1] "foo" "goo" It shall return "foo", "goo" (with or without quotes is fine), where foo and goo are two vectors with numbers. I know this sounds strange, but I'd

Hi, Does anyone know how to manually configure the number of digits printed out from xtable()? For example, I'm exporting a data frame through xtable() into a LaTeX table, I only have two columns in the data frame so by default I only get two decimal places. But I'd like at least 5 decimal places. I had a look at ?xtable() but can't seem to find an example. Cheers, Kevin

Hi, Suppose I have the following lines at the end of a function: answer <- c(2, 1, 0, 4, 5) # In fact, answer will be generate in my # function print(answer) # Print the answer # Now, find the best fitted n degree polynomial print(paste("The best fit is with", which.min(answer) - 1, "-degree polynomial")) this will return:

Hi, Suppose I have: 459 1789 23590 and I'd like to round them to: 400 1700 24000 On the other hand, say if I have: 232 1234 23120 that need to be rounded to: 300 1300 24000 I tried the round(), floor() or ceiling() and can't get what I want. Is there any tricks I can use to achieve this goal? Cheers, Kevin

Hi, I was trying to read in the following data set by using: gas <- read.table("gas.tab", header = T) when I got the error message: Error in "row.names<-.data.frame"(*tmp*, value = row.names) : duplicate row.names are not allowed Any help are appreciated. Thanks, Ko-Kang Wang

Hi, I'm learning Fortran and trying to load a Fortran subroutine into R. I've done: R SHLIB Fibonacci.f and it compiled fine. Then I went into R and done: > dyn.load("Fibonacci.so") > Fib <- function(n) { + .Fortran("Fibonacci", + as.integer(n))[[1]] + } > Fib(5) Error in .Fortran("Fibonacci", as.integer(n)) :

Hi, a couple of simple graphics questions: 1. I have a little function that makes bar plots. Now I would like to limit the Y-axis outside this function (that means after calling the barplot() command) depending on the data to be plotted . Does anyone know how to do this ??? 2. When using barplot() and limiting the yAxis, R draws the bars below the x-axis. How can I avoid this problem ??

Hi, Is there a function in R that does Cleveland's Cut-and-Stack plot (Page 190 -- 191, The Elements of Graphing Data, William S. Cleveland)? Or do I need to do it the hard way, i.e. set par(mfrow = c(m, n)) then do it one-by-one? (I have a time series data set that is almost identical to the description in Cleveland's book, hence I'm interested in trying the Cut-and-Stack plot)

Hi, Is it possible to create a ts() object, whose data is daily based BUT measured only on working days? In other words, suppose I have a data set with 255 observations, measured from 29 June 1959 to 30 June 1960. How would I create such a data? I tried something like: ts(c(...), start(1959, 180)) but I'm not sure what to use for frequency. In other words I don't know how to

Hi, Suppose I have a for() loop that draws 6 boxplots as follows: par(mfrow = c(2, 3)) for(i in 2:length(spam.sample)) { boxplot(split(spam.sample[,i], yesno)) } Where spam.sample is a data frame with 7 columns, and I'm interested in plotting column 2 ~ 7 against column 1 (yesno). The boxplots appeared fine, however I'm trying to add a meaningful title, x and y labels to them.
