Re: [R] error code trying to extract second column from coeftest output
Hi I want to use the standard error values in the summary that is produced using coeftest, but I am getting an error code- any ideas? See what is structure of coeftest object by str(coeftest(lmodT_WBHO)) and from this you shall deduct how to select second column.

Re: [R] error code trying to extract second column from coeftest output
I recommend that you troubleshoot your own problem using the str function... for example, str( coeftest(lmodT_WBHO)). The error message is not a code... it is perfectly readable English, and it is telling you that the result of calling coeftest is not a list with parts that can be pulled out using the $ operator. --- Jeff NewmillerThe . .
