[R] error code trying to extract second column from coeftest output
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? library(lmtest) coeftest(lmodT_WBHO) t test of coefficients: Estimate Std.

[R] vector w/o arithmetic addition for boxplot
Hello, I am having trouble asking R to read individual numeric vectors for a box plot of the residuals of a linear regression. It is performing arithmetic addition on the 16 individual variables that I want individual box plots for. I have 16 race*treatment variables that were created from cleaned data.frames for race and treatment independently: t1W, t1B.t4W, t4B, t4H, t4O. class(t1W) produces numeric (1000 observations of 1's and 0's) To create the box plot I am using boxplot(residuals(IRR)~ treatRace_clean) where I have tried treatRace_clean as both of the following treatRace_clean - as.factor(as.vector(t1W + t1B + t1H + t1O + t2W + t2B + t2H + t2O + t3W + t3B + t3H + t3O + t4W + t4B + t4H + t4O)) treatRace_clean - as.vector(c(t1W, t1B ,t1H ,t1O, t2W , t2B ,t2H ,t2O ,t3W , t3B, t3H + t3O , t4W , t4B , t4H , t4O)) However, I continue to get this error code: Error: $ operator is invalid for atomic vectors Thoughts? -- View this message in context: http://r.789695.n4.nabble.com/vector-w-o-arithmetic-addition-for-boxplot-tp4630190.html Sent from the R help mailing list archive at Nabble.com. __ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
