try this: mat <- matrix(sample(90:2000, 10000, TRUE), 1000, 10)
ind <- rowSums(mat > 100 & mat < 120) > 0 mat[ind, ] I hope it helps. Best, Dimitris mentor_ wrote:
Hi, if I have a large matrix e.g. with the dimensions of 1000 rows and 10 columns. How can I select rows comprising one or more values between a specific range of two values? So e.g. a row has one or more values between the range of 100 - 120. Cheers
