The line is really not "fine" at all since it lies in that word
"purposely."  Also, you've associated "helpful" with unintentional
rudeness.  The distinction you've drawn is clear.

The problem is defining a "toxic environment."  One person can find all
kinds of offense and rudness in something where another would
be appreciating a short, concise response, such as a suggestion to "read
the manual." "Toxic" is personal and one can find it wherever one
looks, if so minded. I suspect that if one perceives rudeness, one
ought to check and see that we haven't left our sensibilities out in
the traffic pattern where they are bound to be trampled.

Look at how much memory is available.  Possibly increase the work space
available to R.  What other software was recently changed immediately
prior to the appearance of the problem.  Lastly, check that hardware it
self.  Most hard drives have diagnostic routines that can be accessed
to check drive integrity.  

The random nature to the fail suggests a memory availability problem -
some newly resident routine that uses more memory than it should.  Run
the Task Manager in monitor memory availability before, and at
failure.  But, I once chased a similar problem all the way to a failing
CPU before fixing it. I essentially rebuilt the computer.

There's a lot of fog in the air.  Properly, the use in the USA is as

The issue is apparently to analyze activity over a 24 hour cycle.  The
OP mentions the use of a camera trap so they are evidently analyzing
trap events by time of event.  The radian constraint is mentioned in
the Activity package docs.

A potentially useful piece of advise is to avoid using MSWord as a text
editor.  I don't use Rcmdr, but text files, particularly CSVs are
extremely useful in R as data files.  Scripts should be pure text as
well.  Word demands that you keep this in mind at all times.  It won't
default to a simple text mode.  You can use notepad, which MS provides
as a stopgap, though I would recommend a more capable programmer's text
editor such as Notepad++, a very useful GPL-licensed text editor for
Windows, which can be downloaded for free.

There are pros and cons as with all things.  RStudio in so far R itself
is concerned is effectively simply a graphic interface for the
terminal.  You operate R from within RStudio essentially the same as
you would from a terminal.  Useful traits include a streamlined means
of installing new packages without trolling through CRAN, quick
displays of data sets and other objects currently in the work
environment, and a very handy way to build scripts for an analysis.
Commands can be run from the Console window and copied to an *.R
script which can then be fine tuned to produce analytical, tabular and
graphical output to files that is readily incorporated into a
comprehensive analysis and report.  Graphics - plots - are created and
buffered in sequence and can be saved from the plot window as image
files or pdfs without adding device() lines to the script.  A nice
addition would be an output window similar to the plot window.  As it
is, I still use sink() to capture output of tables and analytical
results.  RStudio does have some highlighting.  The biggest gotcha is
that R is not precisely the same experience under different
environments (e.g. linux vs. windows).  RStudio is more consistent
across platforms.

RStudio is not an environment like RKward or JGR where analytical tools
are available through a menu.

You are explicitly attempting to place a file named data in your root
directory.  You lack privileges to write into the root directory,
which action is the source of the permission denied message. Good
practice is to use a directory in your user-space such as a
subdirectory of Documents as indicated by Mr. Newmiller. Ideally you
should use getwd() and setwd() locate and set the directory where your

is relatively simple do this under the Session/Set Working Directory

The problem may not be R at all, but rather Windows.  How large is your
drive, not RAM but the actual drive?

If you can, examine your drive to see if there are either fragmentation
problems or hidden files taking up excess space.  Look at the
drive properties for C:\ and run disk clean-up if possible.  Another
problem, MS may have fixed this at some point - I don't run Win 8, is
that if your deleted files are not removed, you can run out of space.
Usually, the space occupied by a file marked for deletion should
be scavenged as Windows needs space, but sometimes that may not happen,
especially with a very full drive. So, if there are files in the
Wastebasket remove them completely.  Another space-use that can grow
to excess is a print spool. Even Windows uses a print spool and that can
grow too large for the system to function efficiently.

 $ ID : Factor w/ 5 levels ID1,ID2,ID3,..: 1 2 3 4 5
 $ age: num  38 35 NA NA NA

SO, the question, is what do you want to do with that column?  An NA
value tells you honestly that the information is missing.  Replacing it
with a zero can be misleading and can bias some basic parameter
estimates.

After you know how you want to treat the data in that field, you may
have a better idea of how to handle the missing data.

You really need to offer more information, e.g. a reproducible example
that includes just how how moved data into your data frame. As
it is, the only reasonable suggestion is to try and find your lost
singleton socks, the missing variablee may be hiding with them.
Alternatively the lost variables may have taken off to Never Never Land
to hang with the Lost Boys.

One simple possibility is that the missing variables were actually
never read in to the data frame.  Have you ever seen those variables
in your data frame?  Did you try str(dataframe)?

As regards hidden and local, you'll - again - have to be a good
deal more explicit.

 The assignment operator is TWO characters: a less than sign

Actually, you can use the = sign as well.

X = 3

works the same as

X - 3

and uses two fewer keystrokes if you're lazy enough to care about such

You really need to pay better attention somewhere.  There are six
variables in your example table for instance, not four.  You state you
want to do something with the serialno variable, but it is not used 
in your bit of code.  Also, given that serialno appears to be
unique in your example, a bar graph would be singularly uninformative.

You need to provide a better example of the data, and an actual example
of the code you are trying to use, including the libraries you've
loaded.

It is not clear what you want.  Why is there an 'x = log' term in
plot()?  If you want to plot log(x) try using:

plot(log(x), y, xlim=c(0.1, 1.2), ylim=c(0.1, 1.2), type=n)

That generates an x/y plot with pies at various points.

Just use a short script.  Install R, install the packages.  To load
them, write a short script, e.g.

#Sets working directory and loads essential libraries.
setwd([working directory here])
library(MASS, aplpack, cclust, ggplot, ...)

Call that from R and provided you have everything where you've R it
was, you're set.

Lianne,

graph can be found here:

http://bioconductor.org/packages/2.12/bioc/

You will need to read the bioconductor instructions.  If you visit the
R Project CRAN site, you can find packages there.  Each package will
have an associated description and a list of depends which are other
packages a specific R package depends upon.  The items on the list are
color coded by source.

It looks like your problem has already been answered, however, as a

for minor variations between what you expected to export and what Excel
really exported as delimited text.  Occasionally there will be a
space or other character (,'/$,- etc.) that maybe handled as
a signal or ignored by the importing program but not by Excel.  Usually
Excel works as expected, but it is a good idea to examine the text
file(s) in an editor like notepad in Windows or Kate in Linux if you
encounter an oddity. BTW, there better choices than notepad for Windows
and I would recommend one with column selecting abilities for work on
delimited data files.
