Dear R Experts, I have written a following function :- myfunction<- function(servername,dbname,dbtablename){ library(RODBC) channel <- odbcDriverConnect("driver=SQL Server;server=servername") initdata<- sqlQuery(channel,paste("select * from dbname .. dbtablename")) return(dim(initdata)) } I have written this function which has input parameters like servername ,dbname and dbtable to connect to Ms SQL server 2005 and get data from the table. Now when I run this function using the f...

What do we expect from the following IR? @i2 = constant i32 30, section "INITDATA", align 4 @i1 = global i32 0, section "INITDATA", align 4 Currently, we stick them in one section that isn't writable which is problematic because @i1 is writable. If you flip @i1 and @i2 you get one section which is writable. It seems like we should do one of the following: 1...

Hi Does anybody know how to create ff objects with data reading from stream objects, such as data reading from PostgreSQL database through RPostgreSQL. For this purpose although we can save the data to a csv file through external tools and then read it through csv readers, but it requires one more data read and write operation, which is of high I/O cost for large datasets.

Greetings useRs, Can anyone provide an example how to use ff to feed a very large data frame to glm? The data.frame cannot be loaded in R using conventional read.csv as it is too big. glm(...,data=ff.file) ?? Thank you Stephen B

Hi, This is the fifth version of this patch series. With the Versatile Express TC2, it''s possible to boot only with A7 or A15. If the user choose to boot with only A7, the CPU ID will start at 0x100. As Xen relies on it to set the logical ID and the GIC, it won''t be possible to use Xen with this use case. This patch series is divided in 3 parts: - Patch 1: prepare Xen
