Hi,
I want to take a look at the sourcecode for balloonplot. I would appreciate it if I could get help on overcoming the following problem :
> methods(balloonplot)
[1] balloonplot.default* balloonplot.table* ?
? ?Non-visible functions are asterisked
> balloonplot.default
Error: object 'balloonplot.default' not found

How do I access the non-visible functions?
Thanks,
Ravi??

xlab, ylab in balloonplot(tab)?
I'm not understanding something.
I'm trying to add xlab & ylab to a balloon plot of a table object. From docs
I thought following should work:
require(gplots)
# From balloonplot example:
# Create an example using table
xnames <- sample( letters[1:3], 50, replace=2)
ynames <- sample( 1:5, 50, replace=2)
tab <- table(xnames, ynames)
balloonplot(tab)

How to use access results of gregexpr in data frames
Hello,
I'm trying to figure out how to find the index of the second occurrence of "/" in a string (which happens to represent a date) within a data frame column.
I've used the following code successfully to find the first instance of "/".
dframe <- data.frame(date=c("5/14/2011", "4/7/2011"))
dframe$x1 <- regexpr("/", dframe[, 1])

How to subset based on column name that is a number ?
Hi,
I have a data frame with column names "1", "2", "3", ... and I'd like to extract
a subset based on the values in the first column. None of the methods I tried
worked (below).
x <- subset(dframe, 1 = = "My Text")
x <- subset(dframe, "1" = = "My Text")
x <- subset(dframe, names(dframe)[1] = = "My Text")

error in NORM lib
Dear alltogether,
I experience very strange behavior of imputation of NA's with the NORM
library. I use R 2.2.0, win32.
The code is below and the same dataset was also tried with MICE and
aregImpute() from HMISC _without_ any problem.
The problem is as follows:

Referencing a vector of data labels in ggplot function
Hi,
I really feel I've looked everywhere, although I know this can't be a hard
problem. I'd like to be able to call the graph below as a function, but I
can't get the function to recognize variables beyond 'dframe'. I've read
through many papers on writing functions in R, but I can't get this to work.

Selecting data frame components by name - do you know a shorter way?
Hi! I suspect there must be an easy way to access components of a data frame by name, i.e. the input should look like "name1 name2 name3 ..." and the output be a data frame of those components with the corresponding names. I ´ve been trying for hours, but only found the long way to do it (which is not feasible, since I have lots of components to select):

Change global env variables from within a function
Hi,
I've looked all over for a solution to this, but haven't had much look
in specifying what I want to do with appropriate search terms. Thus I'm
turning to R-help.
In the process of trying to write a simple function to rename individual
column names in a data frame, I ran into the following problem: When I
rename the columns within my function, I can't seem to get it to

renaming columns
I frequently get data sets with cryptically-named variables. The datasets
are more useful to me with informative variable names. I know that I can
rename variables using the following command:
dimname(dataset[[2]][index.of.variable.to.be.renamed]<-new.variable.name
If I want to do this inside a function (say something I call RenameCol)
what is the best way to communicate the

select columns from vector of column names

I want to extract columns from a data frame using a vector with the desired
column names.
This short example uses the select argument in the subset function to
accomplish what I am trying to do. Is there a better solution?

Finding a vector position using names rather than values
Dear R gurus,
I have been struggling with this for a while and thought you might be able to give me some guidance.
I have a data frame, on which I apply a row function. The result looks to me like a vector that retains the old row names. I then sort the vector and subsequently need to be able to identify the rank of certain values by searching for their row names. See this mock example:

For example, if we define the following data frame containing the level of y observed for 5 patients at three time points:

geom_errorbar with ggplot2

I am trying to build an error bar plot with ggplot2. However, even if

a continuous line linking the different bars.
I attach below the code I used, as well as the data.
