after the driver <- line I get this error: 在驱动程序<-行之后，出现此错误：
driver <- JDBC("com.amazon.redshift.jdbc41.Driver", "RedshiftJDBC41-1.1.9.1009.jar", identifier.quote="`") Error in .jfindClass(as.character(driverClass)[1]) : class not found

this error went away when I downloaded the used the 42-driver, not the 41-driver 当我下载使用的是42驱动程序而不是41驱动程序时，此错误消失了
download.file(' http://s3.amazonaws.com/redshift-downloads/drivers/RedshiftJDBC42-1.2.1.1001.jar ','RedshiftJDBC42-1.2.1.1001.jar') download.file（' http://s3.amazonaws.com/redshift-downloads/drivers/RedshiftJDBC42-1.2.1.1001.jar'，'RedshiftJDBC42-1.2.1.1001.jar '）
Hopefully this will help someone.. on Windows 7 希望这会帮助某人..在Windows 7上
