strange strsplit gsub problem 0 is this a bug or a string length limitation?
...to find why my formula with 113 items, i.e. A1 thru A113, was being truncated and I only get 85 items, not 113. Is it due to a string length limitation in R or is it a bug in the strsplit or gsub functions, or in my string? I'd very much appreciate any suggestions ============Input script: backtestFormula<-SPX~A1+A2+A3+A4+A5+A6+A7+A8+A9+A10+A11+A12+A13+A14+A15+A16+A17+A18+A19+A20+A21+A22+A23+A24+A25+A26+A27+A28+A29+A30+A31+A32+A33+A34+A35+A36+A37+A38+A39+A40+A41+A42+A43+A44+A45+A46+A47+A48+A49+A50+A51+A52+A53+A54+A55+A56+A57+A58+A59+A60+A61+A62+A63+A64+A65+A66+A67+A68+A69+A70+A71+A72+A73+A74+A75+...
