dear memebers,
I am using R in AWS linux instance for my
research. I want to remove certain objects from the global environment to
reduce my EBS cost..for example, I want to remove all objects of class "xts",
"zoo". Is there any way to automate this, instead of
When you understand the strong dependence on how the data controls ggplot,
using it gets much easier. I still have to google details sometimes
though. Note that it can be very difficult to make a weird plot (e.g.
multiple parallel axes) in ggplot because it is very internally
consistent... a
I have the task of producing some boxplot graphics with the requirement
that these have the same general appearance as a set of such graphics
as were produced last year. I do not have access to the code that was
used to produce the "last year" graphics.
There are multiple boxplots per figure
Hmmm. I do get output in the file with the first example, and the second
example is too complicated for me.

Hello,
First of all welcome to R, I hope you enjoy it and that as you go along
it will give less and less troubles.
Now, why would length(56) return 2? It's just one number, a vector of
length 1.
Start by trying it at an R prompt and see the result.
Hope this helps,

You can readily do it yourself:
x <- 56
length(x) # hint: why do you expect length(56) to be 2?
rnorm(length(x))
x + rnorm(length(x))
For more complicated problems, the debugger is useful, but I almost always find
investigating the steps at the command line to be the most informative.

Some of the basic principles:
(1) Whenever you type the name of an R object at the R prompt, it is as if R
wraps whatever you typed inside print().
Debugging in R applies one statement at a time. If you want to debug within a
statement you can "step into" the function calls within the statement or you
can execute the function calls separately and inspect the result. Your function
consists of one statement so the debugger only has one place

Hi everyone,
I am taking my first R course. This was my first example.

something like:

because I expected rnorm to return two

If Sys.which("grep") says that grep is available then system("grep -n ...")

Short answer: do.call()
do.call("rbind", df.list)
will rbind all of the data frames in df.list.
You may have to tidy up row names afterwards, and you will need to make sure
that the data frames all have the same column names and each column has the
same class, or you'll get unexpected results.

Hello,
If you need to go through R the function fread of data.table
can speed up the data import.
If not and you work on a gnu/linux distro may be awk might help
