Hi Kaj, That error means that your fileName parameter needs to be passed as a string. If you instead pass bov_9712 as you have below (with no quotes), R will think that you mean to pass an object that is called bov_9712, (instead of the string "bov_9712") and when it gets to the point where it is ready to try and actually read that file name into R, it will give you the error below. Please let me know if you still have questions.

Hi Kaj, That error means that you have previously tried to make this package (and presumably failed or you wouldn't be trying again). I am guessing that this is probably from when you were passing in the wrong argument type (from when you wrote in before). So what is wrong now is that the old half finished .sqlite file is still in your working directory (which is why there is a metadata table there already). Please delete all files that were generated from when you did this before, and start again. Marc Dear R helpers, I try to to create .db for Bovine Agilent Microarray Ship. R shows me error as indicated >/ library(AnnotationForge) />/ setwd("D:\\Progect for MOU\\Detailed Projects\\Cumulus cell") />/ bov_9712<-read.table("015354_D_GeneList_20061130.txt", sep = "\t", skip=1, /+ header = FALSE, as.is = TRUE, fill=T)[,c(1,5)] >/ write.table(bov_9712, file = "bov_9712.txt", sep = "\t", /+ row.names=F, col.names=F) >/ output="D:\\Progect for MOU\\Detailed Projects\\Cumulus cell\\Annotations" />/ makeDBPackage("BOVINECHIP_DB", /+ affy=FALSE, + prefix="bov_9712gbNRef", + fileName="bov_9712.txt", + baseMapType="gbNRef", + outputDir=output, + version="1.0.0", + manufacturer = "Agilent Technologies", + chipName = "Agilent-015354 Bovine Oligo Microarray") Error in sqliteExecStatement(con, statement, bind.data) : RS-DBI driver: (error in statement: table metadata already exists) Please describe what does the error indicate? and please guide me how to solve it.
