Hi all, I have 2 data frames like the following: the first one df1: 'data.frame': 141obs. of 1 variable: $SerialNum: int 41006 41013 41044 41046 41067 41166 41202 41262 41274 41290 and the second one df2:
'data.frame': 194 obs. of 2 variables: $Serial: int 41006 41013 41018 41044 41046 41067 41111 41200 41262 41331 $Count : int 1 10 103 11 12 13 138 14 15 16 169 18 182 2 20 21 224 226 then I find the intersect of two data frames in serials which is: Matched=intersect(df1$SerialNum,df2$Serial) which gives me matched serials in both data frames. Next I want to get Count of these matched serials from df2 but I don't know how to make the right subset for this! Does anyone know how should I do that?
