[R] complex search between dataframes

[Remko Duursma]

Here is another solution, using apply() and lapply().


# list of sequences corresponding to each row in data1:
seqlist <- apply(data1, 1, function(x)seq(from=x[1], to=x[2]))

# Find which rows of data2 are inside those sequences:
rowsInSeq<- unlist(lapply(seqlist , function(x)which(data2$position %in%
x)))

# use that to index data1:
data2[rowsInSeq,]


greetings,
remko
