Merging data frames on two conditions
...a.frame <- merge(df1,df2, by=c("Col1","Col2"))
It is giving me a null result.
Basically I need to apply two conditions.
I also tried sqldf but it is running forever. Will indexing help ?
temp <- sqldf("select a.chr,a.SNP,a.snp_qual,a.rms_qual,a.depth,b.rsid FROM
+ data_lane6_snps a,
+ data_lane6_snps_rsid b
+ WHERE
+ a.SNP = b.SNP
+ AND
+ a.chr = b.chr
+ ")
Thanks!
