[R] Not getting correct graphs

[Sri krishna Devarayalu Balanagu]

Hi all,
Can anybody debug the following programme, as I am getting some Junk graphs in the pdf.
Please find the attached raw data file.
Thank you
Regards
Rayalu


library(ggplot2)
setwd("D:\\General Check list")
library(RODBC)
conn <- odbcConnectExcel ("Book1.xls")
Orange1 <- sqlFetch (conn, "Sheet3")
odbcClose(conn)
rm(conn)

#CDAI Change
unique(Orange1$BSCHSTAT) -> change
pdf("xxx.pdf")
for (j in 1:length(change)){
((Orange1$BASCHGAUT == "8-item scale")&(Orange1$BSCHSTAT == change[j])) -> b
FD <- Orange1[b, ]
unique(FD$REFID) -> refid
for (i in refid)
{
Orange2 <- FD[i == FD$REFID, ]
Orange2$ARM<- factor(Orange2$ARM)
unique(Orange2$BSCHSTAT) -> x
y <- paste("REFID=", i,"; ", "BSCHSTAT=", x, sep="")
print(qplot(TIME1, BASCHGA, data=Orange2, geom= c("line", "point"), colour=ARM, main=y))
}
}
dev.off()
