[R] inner_perc_table?

[William Dunlap]

You need to supply a character string, e.g., "inner_perc_table", that names
the C entry point.  If you supply a name, e.g., entry_point,  or a more general expression,
e.g, entry_points[j], then it will be evaluated with the usual R evaluation
rules and the result must be a character string.

  > getNativeSymbolInfo("inner_perc_table")
  $name
  [1] "inner_perc_table" 

  $address
  <pointer: 0x000000006b1cb650>
  attr(,"class")
  [1] "NativeSymbol"

  $package
  DLL name: nlme
  Filename: c:/Program Files/R/R-2.15.0/library/nlme/libs/x64/nlme.dll
  Dynamic lookup: FALSE

  $numParameters
  [1] 6

  attr(,"class")
  [1] "CRoutine"         "NativeSymbolInfo"

or
  > entry_point <- "inner_perc_table"
  > entry_points <- c("outer_perc_table", "inner_perc_table")
  > identical(getNativeSymbolInfo(entry_point), getNativeSymbolInfo("inner_perc_table"))
  [1] TRUE
  > identical(getNativeSymbolInfo(entry_points[2]), getNativeSymbolInfo("inner_perc_table"))
  [1] TRUE
