I started a brand new session in R 2.10.1 (on Windows). If it matters, I am running the community edition of MySQL 5.0.67, and it is all running fine.
I am just beginning to examine the process of getting timer series data from one table in MySQL, computing moving averages and computing a selection of estimates based on relations among moving averages of different variates, and storing all the results in another table in MySQL. The very first thing I did in this session was execute the following two commands: Sys.setenv(MYSQL_HOME='c:/MySQL') library(RMySQL) The output I got was: Loading required package: DBI Warning message: In inDL(x, as.logical(local), as.logical(now), ...) : DLL attempted to change FPU control word from 8001f to 9001f Now, I write programs in relatively high level languages (C++, perl, Java, and now R), and NEVER even consider twiddling with FPU control words or playing with registers on the processor. I have never gotten this close to the hardware since I messed with video memory in the old days when I wrote computer based teaching materials on DOS and had to get acceptable performance out of the hardware available way back then.. Consequently, I have no idea what this warning means or what I ought to do about it. I assume the DLL it is referring to is libmySQL.dll<http://www.stat.berkeley.edu/classes/s133/libmySQL.dll>, which RMySQL needs. But I have no idea either why it would do what R says it is doing or why it matters to me, or what I ought to do about it. I'd appreciate any info you can provide.
