The follow describes how different packages are used.  


DEPENDS:  

zoo:  Many data objects are of class 'zoo'.  This is used 
extensively in 'FinTS'.    

fUtilities:  'skewness' and 'kurtosis' are called from 
'FinTS.stats'.  The 'fUtilities' skewness and kurtosis 
functions are generic and try to do more things but contain 
bugs.  However, 'fUtilities' is required by 'fUnitRoots'.  
Therefore, it is used for 'skewness' and 'kurtosis' also 
to reduce 'DEPENDS'.  

chron:  component 'date.time' in 'ibm' used in chapter 5 is of 
class 'chron'.  

polynom:  'solve.polynomial' is used by 'plotArmaTrueacf' to find 
complex conjugates.  

fUnitRoots:  Function 'adfTest' is used by 'Unitroot'.  


SUGGESTS:  

moments:  Used in 'ch01.R'.  

distEx:  Used in 'ch01.R'.  

tseries:  Used in 'ch02.R'.  

urca:  Used in 'ch02.R'.  

uroot:  Used in 'ch02.R'.  

fCalendar:  'holidaysNYSE' is used in 'scripts\create-ch08.R', 
'*-ch10.R' and '*-ch11.R'.  

lmtest:  'coeftest' used in 'ch02.R' 

sandwich:  'vcovHC' used in 'ch02.R'

PREVIOUS DEPENDS:  

e1071:  Was used for 'skewness' and 'kurtosis' in 'FinTS.stats'.  
However, these functions are masked by functions of the same 
names in 'fUtilities', which is required by 'fUnitRoots'.  
Since 'fUtilities' is loaded anyway, I chanded 'DEPENDS' to 
use that instead.  I 
Therefore, it's not clear if this is even needed.  

fCalendar:  'holidayNYSE' used in 'scripts\create-ch08.R', 
-ch10.R and -ch11.R.  I don't think it's needed beyond that.  
If not, it should be moved to 'SUGGESTS'.   


PREVIOUS SUGGESTS:  

logSpline:  At one time, this was used in one of the scripts files.  
However, I can't find it now, and I may have deleted it.
