I don't see what's missing in my statements to add rows to a data frame and someone else will probably see what needs to be added to the statements.
The data frame has this structure (without any data): $ PHYLUM : chr $ SUBPHYLUM : chr $ SUPERCLASS : chr $ CLASS : chr $ SUBCLASS : chr $ INFRACLASS : chr $ SUPERORDER : chr $ ORDER : chr $ SUBORDER : chr $ INFRAORDER : chr $ SUPERFAMILY: chr $ FAMILY : chr $ SUBFAMILY : chr $ TRIBE : chr $ SUBTRIBE : chr $ GENUS : chr $ TAXON : chr One command (all on one line) is: itis.ttable <- rbind(itis.ttable, data.frame(PHYLUM = "ARTHROPODA", SUBPHYLUM = "MANDIBULATA", SUPERCLASS = NA, CLASS = "INSECTA", SUBCLASS = "DICONDYLIA", INFRACLASS = "PTERYGOTA", SUPERORDER = "PANORPIDA", ORDER = "TRICHOPTERA", SUBORDER = "INTEGRIPALPIA", INFRAORDER = "PLENITENTORIA", SUPERFAMILY = "LIMNEPHILOIDAE", FAMILY = "LIMNEPHILIDAE", SUBFAMILY = "LIMNEPHILINAE", TRIBE = "STENOPHYLACINI", SUBTRIBE = NA, GENUS = "CHYRANDRA", TAXON = "CENTRALIS")) R's response is to ask for more input by displaying the continuation prompt, +. What am I not seeing that R needs to add this row to the data frame?
