R2MLwiN - 'mlwin.exe' is not recognized

Post by Rakesh84 »

Dear all,



I am currently trying to run a two-level model. I have downloaded the 30-day trial of MLwiN (version 2.30).
The following specifications were set in R:

MLwiN filepath: mlwin="H:/MSc/MSc Project/Project Data/Datasets" ## Is this the correct file path? I am unable to locate the MLwiN.exe file. I can however locate the MLwiN.msi file ##

Dataset: indata15=read.table("mcar15.dat")
Specified Levels: levID=c("school", "pupil") # School=level 2, pupil=level 1
Model: model.mcar15="nlitpost~(0|cons_)+(1|cons_+gend+fsmn+pupil)+(2|cons_+school)"
Estimation method: estoptions=list(EstM=1)
Distirbution: D="Normal"
## Note: The code runs up to this point ##
runMLwiN(model.mcar15, levID, D, indata15, estoptions, MLwiNPath=mlwin)

Following execution of the above, the following output is displayed in R:
> runMLwiN(model.mcar15, levID, D, indata15, estoptions, MLwiNPath=mlwin)
MLwiN is running, please wait......
'mlwin.exe' is not recognized as an internal or external command,
operable program or batch file.
Error in read.dta(MCMCfile) :
unable to open file: 'No such file or directory'
In addition: Warning messages:
1: running command 'C:\windows\system32\cmd.exe /c mlwin.exe /nogui /run C:/Users/RAKESH~1/AppData/Local/Temp/RtmpQXDzgd/macrofile_1df46aaa5119.txt' had status 1
2: In shell(cmd) :
'mlwin.exe /nogui /run C:/Users/RAKESH~1/AppData/Local/Temp/RtmpQXDzgd/macrofile_1df46aaa5119.txt' execution failed with error code 1
>

Can someone please help me to resolve this issue? I have a feeling it may be due to the location of the MLwiN.exe file, however I am having trouble locating this.

Many thanks in advance,
Rakesh

Assuming that you are using a 64-bit version of Windows and have installed MLwiN in the default location then the correct setting for MLwiNPath would be:

Code: Select all

C:\Program Files (x86)\MLwiN trial\i386\mlwin.exe
