cannot plot numeric variables

[DS-Rodrigues]

Hi Chris

The plot does not seem to be working for numeric variables. I get:

vim$numeric_vims$results_by_level
NULL

Not sure if there is a more efficient way to do this, but in plot-var.R, if we replace lines 21-30:

  # Can only plot numerics currently, need to expand to factors.
  numeric_vars = unique(vim$numeric_vims$results_by_level$name)
  factor_vars = unique(vim$factor_vims$results_by_level$name)
  if (var_name %in% numeric_vars) {
    results = vim$numeric_vims$results_by_level
  } else if (var_name %in% factor_vars) {
    results = vim$factor_vims$results_by_level
  } else {
    stop("There is no variable called", var_name, ".\n")
  }

    # Can only plot numerics currently, need to expand to factors.
    factor_vars = unique(vim$factor_vims$results_by_level$name)
    if (var_name %in% vim$numeric_vims$colnames_numeric) {
      results = vim$numeric_vims$vim_numeric[[which(vim$numeric_vims$colnames_numeric == var_name)]]$results_by_level
    } else if (var_name %in% factor_vars) {
      results = vim$factor_vims$results_by_level
    } else {
      stop("There is no variable called", var_name, ".\n")
    }

it works!
