[R] problems editing R console

[Carlos Andrade]

Rosa,

Why not just re-load the .txt file (which I imagine be a data frame) and
then edit?

See: http://www.inside-r.org/r-doc/utils/read.table

*I would imagine something along the lines:*

simulation_results <-  read.table("path_to_text_file_of_simulation")
#Double check the parameters on the function documentation, I don't know
how your data looks like, specially header and column separator.

*For doing something like: *

x.erro = 1.4X+erro



*you would just need to use:*
simulation_results$x.erro <- 1.4*simulation_results$X + simulation$erro

*then save the simulation_results variable again.*
