Hello Gurus,
I'm using one of the function, i.e. extractModelParameters, from the
MplusAutomation package to read parameters fromMplus out files into R. I have
360 cells and each cell has several out files (max. 100). I'm extracting the
model parameters from each cell and doing subsequent calculations, primarily, on
'est.' column. The following code demonstrates how I'm extracting
the parameters
and referencing the est. column:
CurrentDir =
paste("D:/Dissertation/Mplus_Output_2Class_LGMM/",a,"-",b,"-",c,"-",d,"-",e,"-",f,
sep="")
modelResults <- extractModelParameters(CurrentDir, recursive=FALSE,
dropDimensions=TRUE)
numReps = length(list.files(CurrentDir, pattern="*.out"))
after the above code is executed, 'modelResults' has all the data from
the out
files as different elements of the returned list. I'm accessing est. column
from
each element in the following way:
for (g in 1:numReps)
MeansTempC1[counterC1] <- modelResults[[g]]$est[31]
I'm able to get the values from the est. column successfully for 359 cells
which
consist of 29532 out files. For just 1 particular cell, when I try to access
the est. column or any other column in that out file, i.e. est_se or
paramHeader, i get the value of NULL and I'm not able to figure out why. The
same code is working for 29532 out files but not for 70 files in that 1 cell. I
would really appreciate if you can assist me troubleshoot this issue. I have
been working on this problem since last Sunday and after spending 6 days I still
not able to figure out the problem.
Your help is truly appreciated.
Regards
Vaib
