Error creating GlobalSoilMap object (GSIF package)

Dear All,
I have been trying to follow this tutorial on 3D modelling of soil with the
GSIF package:
http://gsif.isric.org/doku.php?id=wiki:tutorial_eberg

(code on:
https://code.google.com/p/gsif/source/browse/trunk/eberg/tutorial_eberg.R)

When I get to creating a GlobalSoilMap object (line 181):

SNDMHT.gsm <- GlobalSoilMap(sd.ll, varname="SNDMHT", period=c("1999-02-01",
"2001-07-01"))

I get an error saying:
Error in GlobalSoilMap(sd.ll, varname = "SNDMHT", period = c("1999-02-01",
: unused argument (period = c("1999-02-01", "2001-07-01"))

I think the tutorial is quite old. I checked the help and then replaced
"period" for "TimeSpan". I now get the following error:
 Error in initialize(value, ...) :
  invalid name for slot of class "GlobalSoilMap": TimeSpan.begin


Here is some information on this function:

GlobalSoilMap function (obj, varname, TimeSpan = list(begin = Sys.Date()

- 1, end = Sys.Date())) { if (!class(obj) == "list") { stop("Object of
class 'list' required") } out = new("GlobalSoilMap", varname = varname,
TimeSpan.begin = TimeSpan, sd1 = as(obj[[1]], "SpatialPixelsDataFrame"),
sd2 = as(obj[[2]], "SpatialPixelsDataFrame"), sd3 = as(obj[[3]],
"SpatialPixelsDataFrame"), sd4 = as(obj[[4]], "SpatialPixelsDataFrame"),
sd5 = as(obj[[5]], "SpatialPixelsDataFrame"), sd6 = as(obj[[6]],
"SpatialPixelsDataFrame")) return(out)
}

Any ideas?
Thanks.

Hello,

According to the help file, TimeSpan is an "object of class "list";
contains begin and end of the sampling period of class "POSIXct"". You
need to provide a list of POSIXct dates, not a vector.

Thanks for the suggestion, but I am still getting an error:

 > SNDMHT.gsm <- SoilGrids(obj=sd.ll, varname="SNDPPT",

TimeSpan=list(begin="1999-02-01", end="2001-07-01"))
Error in validityMethod(object) :
   no slot of name "TimeSpan.begin" for this object of class "GlobalSoilMap"

I am on Windows 8 using GSIF version 4-01. I will try to load this on a
Ubuntu Virtual Machine to see if it turns out differently.

    I would recommend switching to using "SoilGrids" class:

    http://gsif.r-forge.r-project.__org/SoilGrids.html
    <http://gsif.r-forge.r-project.org/SoilGrids.html>

    Hence, to produce objects of SoilGrids class you need to use:

    ## save to a "SoilGrids" object:
    SNDMHT.gsm <- SoilGrids(obj=sd.ll, varname="SNDPPT",
                  TimeSpan=list(begin="1999-02-__01", end="2001-07-01"))

    In which case TimeSpan needs to be a list with names "begin", "end".

    To install the most recent version of the GSIF package (v0.4-2),
    please use:

    install.packages("GSIF", repos="http://R-Forge.R-__project.org
    <http://R-Forge.R-project.org>")

    For technical issues and problems with SoilGrids classes please also
    consider writing to the GSIF mailing list at:
