Hi all: I have two data sets. Set A includes a long list of hits in a single column, say: m$V1 10 15 36 37 38 44 45 57 61 62 69 ...and so on
Set B includes just a few key ranges set up by way of a minimum in column X and a maximum in column Y. Say, n$X n$Y 30 38 # range from 30 to 38 52 62 # range from 52 to 62 I would like the output to be the rows containing the following columns: m$V1 36 37 38 57 61 62 I am interested in isolating the hits in data set A that correspond to any of the "hotspot" ranges in data set B. I have downloaded sqldf and tried a couple things but I cannot do a traditional merge since set B is based on a range. I can always do a manual subset but I am trying to figure out if there is anything more expedient since these df's will be quite large. Thanks!
