R help - Oct 2016 - Having trouble with running ldBands in Hmisc package. Posted in StackExchange

I am trying to run the example from Hmisc package in RStudio environment under
Windows 10 and downloaded ld98.exe> .libPaths()Produces the following
output[1] "C:/Users/username/X1_Carbon/Documents/R/win-library/3.2"[2]
"C:/Program Files/R/R-3.2.5/library"I moved the ld98.exe to
C:/Users/username/X1_Carbon/Documents/R/win-library/3.2Then installed Hmisc and
ran the following> require(Hmisc)
> b <- ldBands(5, pr=FALSE)Produces the followingError: could not find
function "ldBands"To see if ld98.exe is working in the directory I ran
the ld98.exe in the Windows environment I get the following outputProgram for
computations related to group sequential boundaries using spending functions.Is
this an interactive session? (1=yes,0=no)yes interactive = 1etc.....

You should check the NEWS file. That function was removed in Hmisc version 3.14

Hi,

Just to augment David's reply with some additional direction, if you
specifically need the Lan-DeMets methodology.

The Clinical Trials Task View:

  https://cran.r-project.org/web/views/ClinicalTrials.html
<https://cran.r-project.org/web/views/ClinicalTrials.html>

provides names of other packages that provide for group sequential boundary
calculations, although it looks like the entry for Hmisc needs to be edited
there. I am cc'ing the CT TV maintainer here as a heads up.

Regards,

Marc Schwartz
