variable driven summary of one column
Hello,
how can I get a variable driven summary of one column of my data.frame?
Usually I would do
> summary(data$columnname) to get a summary of column named
"columnname" of my data.frame named "data".
In my case the columnname is not static but can be set dynamically.
So I save the chosen columname in something like
variable <- "columnname"
but how can I

summary of rpart-Object in tktext window?
Hi,
is it possible to put a summary of an rpart-Object into a tktext-window?
Here is what I'm trying to do:
fit <- rpart(Kyphosis ~ Age + Number + Start, data=kyphosis)
tt <- tktoplevel()
tex <- tktext(tt)
tkpack(tex)
tkinsert(tex, "end", summary(fit))
But since the summary of an object is a list, I always get back the
following error-message:

remove multiple columns by name from dataframe
Hi there,
I'm trying to remove multiple columns by name from a data.frame. As a
result I need to get back the modified data.frame without the removed
columns. My columns I want to delete are listed in a vector called
"delete".
data <- read.csv2("data.csv")

boxplot with log="y" and values starting at 0
Hi,
I'm working with a data.frame containing values between 0 and 22000.
Most of the values are actually between 0 and 50 and the high ones are
outliers.
I want to generate a boxplot and since the outliers are extremely
high, I need to scale the y scale logarithmically. Otherwise one
wouldn't really see the boxes of the boxplot.

calling a function with dynamically generated buttons
Hallo,
I'm dynamically generating buttons depending on the number of rows of
my dataframe. Every button is supposed to call a function which
generates a plot with the values of one of my dataframe rows.
My code looks like this:
base <- tktoplevel()
plotten <- function(mat, namen, titel) {
midpts <- barplot(height=mat, names.arg = namen, main =
titel, las=2)

Copy & Paste from tktext on Mac
Hi there,
a text Window is supposed to map the shortcuts for copying and pasting
(<Ctrl-C>, <Ctrl-V>) automatically.
I'm working under Mac OS X and my text window doesn't really map these
functions automatically - it works fine under Windows. Is there an
easy way to map copy&paste functions to a text window under Mac OS X?
This is what I'm doing with my text

summary of summaries
Hi,
I have a few hundreds files with numerical information of different length
but with the same column structure. I use the following code to get summary
statistics
fplist <- list.files(pattern=".*analysis")
for (fp in fplist){
x2 <- read.delim(fp)
summary(x2)
}
Summary gives something like:

Hi,
Why when I do a summary on a table it cuts off the other variables? It says
Other :58 or Other: 120.
how can I get the summary for all the variables under ServLoad.Task and

Thanks,

weird behaviour of summary.default
Hi all.
I may missing something here, but if I do summary.default(1:9999), I get:
Min. 1st Qu. Median Mean 3rd Qu. Max.
1 2500 5000 5000 7500 9999
but if I do summary.default(1:10001) I get:
Min. 1st Qu. Median Mean 3rd Qu. Max.
1 2501 5001 5001 7501 10000
i.e. Max is rounded to 10000.
What's wrong?

Transforming results of the summary function

I have a question about transforming the data from summary function.
Let's say I have a data frame like this:

> x

I think the rule is that you can do anything as long as you don't
complain. If you want to complain, you must follow the instructions.

It seems that there's a bug in summary, in the max. output... but max() alone

Apparent bug in summary.data.frame() with columns of Date class and NA's present
Hi all,
Based upon an exchange with G?ran Brostr?m on R-Help today:
https://stat.ethz.ch/pipermail/r-help/2016-February/435992.html
there appears to be a bug in summary.data.frame() in the case where a data frame contains Date class columns that contain NA's and other columns, if present, do not.
Example, modified from R-Help:
x <- c(18000000, 18810924, 19091227, 19027233, 19310526,

summary.default rounding on numeric seems inconsistent with other R behaviors
I was wondering if it would make sense to change the default behavior of the following:

## Min. 1st Qu. Median Mean 3rd Qu. Max.
## 15560 15560 15560 15560 15560 15560
summary.default on numeric values rounds values (not just presentation) to getOption("digits")-3L (or four) digits by default, making those values surprising and less suitable for

mixed formatting of integer and numeric (e. g., by summary.default())
Hello, eveRybody,
I've been trying to find the origin for the following
formatting-"inconsistency":
E. g., look at the number of digits in summary.defaults()'s output when
NAs occur: in my example below the number of NA's is displayed as an
integer, the rest as numeric (floating point numbers):
> summary.default( c( 1:2, NA))
Min. 1st Qu. Median Mean 3rd Qu.
