Sorry forgot to mention that you probably are better of using <= and >= instead of ==
Br. Frede Sendt fra Samsung mobil -------- Oprindelig meddelelse -------- Fra: mamuash bukana Dato:08/04/2014 15.51 (GMT+01:00) Til: r-help@r-project.org Emne: [R] locating a data value in 3-dimensional data set I have a 3-dimentional data set with dimensions "longitude", "latitude", and "time". Unfortunately, when I look at the range of values in the data set, I noticed some very extremely large(positive and negative) values which are unexpected to be there. So I wanted to point-out the location (lon, lat and time) which these extreme values correspond to in order to see what is happening there. But I could not point-out these grid points and time. I tried: which(3ddata==x) # 3ddata is name of data set, x is the observed extreme value But this couldn't help me. Any suggestion please?
