Is there a way to do text plots in R? I'd like to do some simple XY plots in R with the output in text (ascii). For example, with gnuplot I can do the following: echo 'set terminal dumb ; plot sin(x)' | gnuplot To generate a simple sin wave. Since I connect to a remote Linux machine using SSH, being able to generate a rough idea of what a plot will look like in text would be

Hello all, How can I increase/decrease the line length for screen wrapping? Currently when I run the following the output appears to wrap at just under 80 columns: > c(1:100) [1] 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 [19] 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 [37] 37 38 39 40 41 42 43 44 45 46 47 48 49

Hello everybody, I think my question has been asked before but I am posing it once again since I need it.

Why am I getting the error "Error: cannot allocate vector of size 512000 Kb" on a machine with 6 GB of RAM? I'm playing with some large data sets within R and doing some simple statistics. The data sets have 10^6 and 10^7 rows of numbers. R reads in and performs summary() on the 10^6 set just fine. However, on the 10^7 set, R halts with the error. My hunch is that

Is there a way to stream data into R so that it can be used in a command pipe? Most Unix commands read data via standard input and read the script from the command line. For example: $ seq 1 10 | sed -e 's/^/foo /' $ seq 1 10 | awk '{print "foo " $1}' $ seq 1 10 | perl -lane 'print "foo $F[0]"' In contrast, R seems to read the script

Is there a cheat-sheet anywhere that describes how to do SQL-like manipulations on a data frame? My knowledge of R is rather limited. But from my experience it seems as though one can think of data frames as being similar to tables in a database: there are rows, columns, and values. Also, one can perform similar manipulations on a data frame as one can on a table. For example:

Hi All, I am trying to shift from running mixed models in SAS using PROC MIXED to using lme4 package in R. In trying to match the coefficients of R output to that of SAS output, I came across this problem. The dataset I am using is this one: http://support.sas.com/documentation/cdl/en/statug/63033/HTML/default/viewer.htm#statug_mixed_sect034.htm If I run the following code: proc mixed data=rc

While downloading the R 1.4.1 for windows from the zip file, I downloaded a zip file rw1041m.zip which consisted of .Rd files. Could anybody tell what are these files for? ______________________ Indrajit SenGupta Department Of Statistics St. Xavier's College Calcutta University indra_calisto at yahoo.com indrajitsg at vsnl.net ______________________ EC- 195 Salt Lake City, Sector -1 Calcutta

We need help.... We are doing a project for a statistical class in and we are looking at world record times in different running events over time. We are trying to fit the data with a negative exponential but we just cant seem to get a function that works properly. we have on our x-axis the date and on the y-axis the time(in seconds). So as you can imagine, the times have decreased and appear to

Hi All, I am trying to learn Neural Networks. I found that R has packages which can help build Neural Nets - the popular one being AMORE package. Is there any book / resource available which guides us in this subject using the AMORE package? Any help will be much appreciated. Thanks, Indrajit

I participate peripherally on a listserve for middle- and high-school science teachers. Sometimes questions about graphing or data analysis come up. I never miss an opportunity to advocate for R. However, the teachers are often skeptical that their students would be able to issue commands or write a little code; they think it would be too difficult. Perhaps this stems from the Microsoft- and

Hello again, I'd like to determine if an Excel file is open or writable. Can anyone help me with that? I write some stats to an .xlsx Excel file using the xlsx package. I can't write to the file unless its closed. How do I determine if the .xlsx file is open or closed so I can write to it? I've looked at file.info and file.access and I couldn't get those to work for me. Any

My Mail StationeryDear R- users, I have a small question on R. The other day I was using R when I decided to quit and when I was prompted with the question whether I would like to save the workspace image, I accidently pressed yes and after that every time start R the previous work space gets loaded. How do I avoid this? Thanks in advance, ______________________ Indrajit SenGupta Department Of

RSpec-ers: I''m aware this is quite the FAQ. I have probably asked it myself, but I just can''t Google up anything but others asking it. I grabbed the source to Beast, to use as a Rails project uninfluenced by me, or RSpec. Then I installed the CURRENT version of RSpec and rspec_on_rails, and set up a model spec on Post.
