Re: [R] Making a markov transition matrix
Ajay--you seem to have gotten your question answered regarding putting your
dataframe in the correct format, etc. If you haven't already, you might
want to check out the MSM package for multi-state Markov and hidden Markov
models in continuous time. It's been quite useful for some of my work
regarding estimating Markov chains/matrices and is actively maintained.
Thanks,
Charles

Folks,
I am holding a dataset where firms are observed for a fixed (and
small) set of years. The data is in "long" format - one record for one
firm for one point in time. A state variable is observed (a factor).
I wish to make a markov transition matrix about the time-series
evolution of that state variable. The code below does this. But it's
hardcoded to the specific years that I observe. How might one
generalise this and make a general function which does this? :-)
-ans.
set.seed(1001)
# Raw data in long format --
raw <- data.frame(name=c("f1","f1","f1","f1","f2","f2","f2","f2"),
year=c(83, 84, 85, 86, 83, 84, 85, 86),
state=sample(1:3, 8, replace=TRUE)
)
# Shift to wide format --
fixedup <- reshape(raw, timevar="year", idvar="name", v.names="state",
direction="wide")
# Now tediously build up records for an intermediate data structure
try <- rbind(
data.frame(prev=fixedup$state.83, new=fixedup$state.84),
data.frame(prev=fixedup$state.84, new=fixedup$state.85),
data.frame(prev=fixedup$state.85, new=fixedup$state.86)
)
# This is a bad method because it is hardcoded to the specific values
# of "year".
markov <- table(destination$prev.state, destination$new.state)

Re: [R] Graphics on MacOSX
Yet another approach is to create a postscript file on R for MacOSX and
convert to a windows metafile is:
> postscript("test.ps", width=5.0, height=6.0, paper="special")
> xyplot(1~1)
> dev.off
Then, using the "free"/included MacOSX bundled software, GraphicConverter,
convert the just-created postscript file to a WMF, (Windows Metafile
Graphics), format. (This software has a batch conversion utility for
converting multiple graphs--just select the multiple files and off you go.)
Then, just import the newly converted .wmf files as you normally would into
MS Word/MS Powerpoint. One (tiny) detail, though, is there is a bit of
cropping you may have to do as the paper size, at least on mine, defaulted
to letter, (which is the default). The paper size did not restrict itself
to the 5"x6 " I specified earlier, but rather just the image size, (as
advertised in the documentation.)
However, the final printed product is as you wish--quality commensurate with
the Win32 version.
Good luck,
Charles

You could try creating a PNG with bitmap() using a high resolution,
e.g.,
bitmap("test.png", type = "png256", res = 1200)
plot(1:10, rnorm(10))
dev.off()
Preview can read the resulting PNG file just fine and the Windows
version of Office can insert PNGs, displays them well, and allows
resizing. (I don't have an OS X version of Office so can't test that
the OS X version would handle the PNGs equally well but I would have to
assume it does.)
bitmap() requires Ghostscript which I have installed on my system in
/usr/local/bin. I'm not sure whether Ghostscript came with OS X or if I
installed it myself but it's freely available.
Hope this helps,

[R] Reading Dates in a csv File
Hi all. I'm reading in a flat, comma-delimited flat file using read.csv. It works marvelously for the most part. I am using the colClasses argument to, basically, create numeric, factor and character classes for the columns I'm reading in. However, a couple of the fields in the file are date fields. I'm fully aware that POSIXct can be used as a class, however the field must obey, (I think), the standard/default POSIXct format. Hence the following question: Does anyone have a method they can share to read in a non-standard formatted date to convert to POSIXct? I can read it in then convert it, but that's a two pass approach and not as elegant as a single pass through read.csv. I've read, from the documentation, that "[o]therwise there needs to be an as method (from package methods) for conversion from "character" to the specified formal class" but I do not know and have not figured out how to do that.

Re: [R] R packages on Mac
Hi Sam. I have R 2.0.0, (haven't upgraded to 2.0.1 yet), on my Mac Powerbook 17" and it works like a complete champ. I've had no trouble whatsoever w/installing it, packages or the like. In fact, IMHO the good folks on the dev team for R have a bit more of a GUI for Mac than even for Windows, (def not trying to start a debate here.) Also, as an aside, I was prev running, FreeBSD 4.10 and could not install a few R packages due to the fact that I was running an older gcc compiler, (2.95 to be exact.) Since Mac's gcc is gcc 3.x, (3.2 I think), I've had no probs installing/compiling packages for R. So, from my POV, you really can't go wrong w/a Mac OSX product. I heartily recommend it as a user-friendly UNIX platform for R and related analytics. If you've specific questions, reply back to me or the newsgroup. There is an open source package called Fink, (http://fink.sourceforge.net/), which you will find invaluable for installing some of the base software(s) that may be req for some R packages such as the gcc Fortran compiler. It's a snap to install sources using Fink and it does all the managing for you. Fink is the Mac analog of Debians "apt" package manager. Good luck and, should you choose to go with Mac I'm relatively confident you will not be disappointed.

RE: [R] JDBC DB access in R
Hi. One thing you might also want to consider is the RDBI/RdbiPgSQL suite at GRASS found at http://grass.itc.it/statsgrass/r_and_dbms.html. These are PostgreSQL drivers. For MySQL, just use the DBI and RMySQL found on CRAN at http://cran.at.r-project.org/src/contrib/PACKAGES.html. I primarily run R on Win32, FreeBSD and Mac OSX. The DBI PostgreSQL drivers work impressively well on the FreeBSD/Mac OSX platforms, (which are "kissing cousins", per se.) As Prof Ripley alluded to, using Java sounds hard just to retrieve a dataframe and there are, IMHO, far easier ways to pull data. On Win32, RODBC works well, however I found absolutely no joy on FreeBSD and PostgreSQL. I have used RODBC on Win32 to pull MS SQL, MS Access, Teradata, etc. predicated that there are appropriately installed ODBC drivers for them on your PC. FYI, I work for a really large bank and my group is basically a "SAS shop" as well. While SAS is great at some things, I argue R is better for others. So, while as not to start a thread on R vs. SAS merits, I wish you luck integrating R in your work/workplace. It's a great/powerful analysis language/package whose adoption I hope continues to expand. Charles -Original Message- Thanks for the reply - thru R i have large data sets in oracle, mssql, postgres and we have jdbc drivers for all of them - most of these systems are on UNIX/LINUX and ODBC is not used - we use JDBC to hit the DB's usually in java applications we have. other than that we are a large SAS shop and i am trying to find an alternative to SAS, i think R has a good chance. For R and SQL - i assume using the wrapper below is the easiest way to hit databases via SQL - are there any other ways i am missing? or is JDBC route the easiest when ODBC is not available? not sure if R contains some standard database routines that i am not seeing? also does R have some good data manipulations function - if so, could you point me in the right direction (similiar to DATA steps in SAS) -thx!

Re: [R] Another NEWBIE
Hi Frank. I am (somewhat) new to R as well, but almost a 10 yr SAS veteran. I work for a very large US Bank and have spent a considerable part of my career in Corp Mktg leveraging data for, arguably, data mining, next purchase, attrition, balance diminishment and the like. I am now managing an Operations Research group in their Customer Service and Support (aka Telephone/Call Center Support) within the forecasting and analytics group. What I have found, broadly and personally, regarding R vs. sAS is the following: 1. You simply can't beat the price of R vs. Insightful Corp.'s S-Splus, not to mention SAS. 2. The support folks for R are among the very best, (e.g., most helpful, energetic and enthusiastic to help) 3. R is far, far leaner from what I have seen thus far for modeling, binning/discretizing, graphing, etc. vs. SAS. 4. SAS is, per a previous post, (quite debatably) superior for manipulation and handling of fantastically large datasets. I have found that R's strength is not really in merging datasets and dataset manipulation. Although, major caveat here, it greatly depends on what you need done to the data. For lagging, diffing, binning, R is superior. For match merging, at this stage, I vote for SAS. (Again, I stress I've only 6-8 mos of moderate R experience.) 5. The challenge with R is, perhaps, it's very strength--language density. Once I learn how to do something in R vs. SAS, R's code is fractionally as large as SAS. Literally, it may take 10 lines of code in SAS vs. a one liner in R. That's powerful. However, due to my SAS experience, I've banged out the SAS code and am still looking/hunting for the R equivalent. However, once doing so, it's, borrowing from a popular vegetable drink slogan, "Wow, I could have done that in R." 6. And, lastly, while R is well documented, I seem to find one of the areas of documentation somewhat lacking is a great big R "recipe" book. (Suggestions, BTW, are welcome here.) Documentation of the R language is in place with more being published, (alongside S-Plus), annually. However, there does not appear to be, for example, an "R Transition Recipes for Experienced SAS Users" book. That, ultimately, is what would help me, (I think.) Again, the issue really is simply learning and using the language. Experienced R users, I'm convinced, could do everything R I'm doing in SAS, (with money left over for a few coffees at Starbuck's). In conclusion, I still think that, given one's budget and projects, there's a place for SAS and R to co-exist. But, that paradigm diminishes as (1) the size of the datasets become smaller and, (2) your problems are more academic/researchy/specific in nature. For graphing, esp. w/the Lattice package, R is simply superior (IMHO), period, to SAS. (For some reason, SAS has just not felt the need to improve their graphics, at least the SAS/Graph part of their offering.) And, for the SAS lovers out there, this opinion is mine only as I continue to be primarily a SAS client attempting to transition to R. Frank, while I've probably been too wordy, I've attempted to provide another perspective for you. Good luck.

I think, I mainly thought to understand the difference between SPSS /SAS and R, but didn't really get the point (what explains the question, wich metods R can't do). Maybe, because I don't have much experience with programming (near to none). My background in stats goes also only back to indroductory classes and an advanced course in multivariate statistics. To this, I'm working with Hair, Anderson, Tatham & Blacks's "Multivariate Data Analysis" (5th Ed.) as my ressource, mainly with questionnaire analysis (Reliability Analysis and Factor Analysis, also MDS, Conjoint etc. plus sometimes standard MANOVA, Multiplke Regression etc.). So, maybe my stats aren't sophisticated enough to use R, I'm just a standard user of applied statistical methods, not an academic researcher or even a statistician. It was mainly a descision by costs, because R is free software. With the concept, I completely mistook the R concept as a programming environment more as a kind of advanced SPSS Syntax (because I also would call it "programming" when using it), which I now know, is completely wrong.

yes, another default bg color such as "white" or "transparent" would be
great as I am definitely not a fan of the standard "gray" either. I
researched how to default it to something else, but it seems to have to be
done manually when a lattice/trellis graph is fired up. Strange, though, as
the standard/base graph/plotting does default to a "white" background.

Hi. Another curious observation. When executing the following: > trellis.device(bg="transparent") > xyplot(1~1) I can then copy and paste in MS Word fine.

RE: [R] Printing Lattice Graphs from Windows
Hi folks. It looks like it's stirred some discussion ultimately
resulting/concluding that this phenomena is a possible bug either in the
lattice package or in R 1.9.0/1.9.1 itself. So, I'll stay tuned, so to
speak, for either an update in the lattice package or R as it seems that
that's where the bug may lie. FYI, the resulting plot, (e.g., plot(1~1)),
worked as it should either printing or as a copy and paste as a metafile
which causes me to believe it's in the lattice package.
I appreciate you guys looking into this. (As you may/may not, for some us
corporate folk, data mining is (1) pulling data, (2) producing a graphical
representation of a story/hypothesis from the data and (3) pasting it into
MS Word and/or MS PowerPoint for presentation quickly. So, to much of you
all's potential satisfaction, a number of us use R instead of S-Plus.)
Thanks,
Charles

Hi, Duncan:
I just did "plot(1:2)" in Rgui.exe, and that copied fine as a metafile
into MS Word via the clipboard.
Then I exited and restarted Rterm.exe under ESS and tried it again.
This time, I got a blank image copied into MS Word. However, after I
modified the Lattice defaults via, "trellis.par.set('background',
list('white')); trellis.par.set('plot.symbol', list(cex=0.8, col=1, font=1,
pch=1))", I was able to copy the results of "xyplot(1~1)" as a metafile into
Word.
Unfortunately, when I tried modifying the Lattice defaults the same way
under Rgui.exe. I again got a blank image copied into Word.
hope this helps. spencer graves

Yes, definitely. Can someone distill this down to code that uses only the
base packages (e.g. just grid)? Lattice is a recommended package, so I'd
refer you to its maintainer, but it's probably something in a base package
that's going wrong.
Once you've done that, please submit it as a bug report with reproducible
code. I've never looked at the Windows metafile device driver, so it's
unlikely I'll fix this by 1.9.1, but it is something that should be fixed.

[R] Printing Lattice Graphs from Windows
Hello. I have researched this topic and have found no answers. I am running R 1.9.0 and am trying to print a lattice graph, (e.g., xyplot(1~1)), using mouse right click -> print. It produces a blank page. Also, I right clich, copy the metafile and paste into a MS Office document, (e.g., .ppt, .doc) and, same thing, a blank. I have updated to the latest lattice package and still no printing. Any help/advice?

[R] RODBC on FreeBSD 4.9
Hello. I have found a number of posts/threads on this subject and remain unsuccessful to determine the solution. In brief, my situation is: 1. Running FreeBSD 4.9 Stable in x86 2. Installed, and running, R 1.8.1 3. Installed, and running, postgreSQL 7.4.2 4. Installed, and running, unixODBC 2.2.8 5. Failed, repeatedly, to install RODBC. The following is my error log: tsunami# R CMD INSTALL RODBC * Installing *source* package 'RODBC' ... checking for gcc... gcc checking for C compiler default output... a.out checking whether the C compiler works... yes checking whether we are cross compiling... no checking for suffix of executables... checking for suffix of object files... o checking whether we are using the GNU C compiler... yes checking whether gcc accepts -g... yes checking for gcc option to accept ANSI C... none needed checking for library containing SQLTables... no configure: error: "no ODBC driver manager found" ERROR: configuration failed for package 'RODBC' ** Removing '/usr/local/lib/R/library/RODBC' I have set up the DSN/databases using ODBCConfig, viewed/confirmed through DataManager and have even used isql to further confirm that all is set up correctly.

Also, I found, and employed, the results from a previous post, https://stat.ethz.ch/pipermail/r-help/2001-October/014693.html, and reset my LIBS and LD_LIBRARY_PATH to those suggested by the author. Again, no joy. So, any thoughts, with successful ones perhaps resulting in an FAQ/how-to, would be most appreciated.
