I need to pick from a dataset those rows that have a double value set to 100. However since the values in this column are like the following:
[1] 121.11750 89.36188 115.44320 99.44964 92.74571 107.90180 [7] 138.89310 125.14510 81.61953 95.07307 88.57700 94.85971 [13] 88.96280 114.11430 100.53410 120.41910 114.42690 … Then can I match against 100 or 100.0? Or do I need to match against 100.00000 or something else? E.g. does 100.0 %in% kidmomiq$mom_iq produce a truthful match result with this kind of data (I’m getting 0 occurrences, which might be correct, but I’m not sure)? ______________________________________________ R-help@r-project.org mailing list -- To UNSUBSCRIBE and more, see https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
