Hi R User, I was trying to convert a decimal value into integral (whole number). I used round function but some of the cells have the value less than 0.5 and it converted into 0. But I wanted these cell to have 1 instead of 0. Another way, I could multiply by 10. But l did not want it because it affected my results later. I was wondering about how I can convert 0.2 to 1. For example data<-structure(list(site1 = structure(1:4, .Label = c("s1", "s2", "s3", "s4"), class = "factor"), A = c(0, 2.3, 2.6, 1.3), B = c(0.5, 0.17, 2.9, 3)), .Names = c("site1", "A", "B"), class = "data.frame", row.names = c(NA, -4L)) output<-structure(list(site1 = structure(1:4, .Label = c("s1", "s2", "s3", "s4"), class = "factor"), A = c(0L, 3L, 3L, 2L), B = c(1L, 1L, 3L, 3L)), .Names = c("site1", "A", "B"), class = "data.frame", row.names = c(NA, -4L)) Thanks for your suggestions in advance. cheers, KG [[alternative HTML version deleted]]
