[R] Problems bootstrapping multigroup SEM

Hello, I am having difficulty resolving an error I receive trying to bootstrap a multigroup SEM. The error (below) indicates that the model called to bootSem doesn't contain matrices. This is true, sort of, because I created a list of two covariance matrices for the model to call. All of this

[R] Error in quantile.default(resids) : missing values and NaN's not allowed if 'na.rm' is FALSE

About a year ago I ran some analyses using lmer. The general syntax was: mlm - lmer(var1 ~ (1|dyad) + var2 + var3*var4*var5, na.action=na.exclude); summary(mlm) The model ran fine and I saved the output. I've recently turned back to those analyses, however, the model no longer runs. I get the

Re: [R] Averaging column scores when participants vary in number of observations

I have a data set that includes the identity of a number of Video Coders who scored participants' behaviors in a video. Every participant was scored once, but some participants were randomly assigned to have their data scored twice so I could calculate inter-rater reliabilities. I have completed

[R] Looping Through List of .csv Files to Work with Subsets of the Data

Hello, I want to subset specific rows of data from 80 .csv files and write those subsets into new .csv files. The data I want to subset starts on a different row for each original .csv file. I've created variables that identify which row the subset should start and end on, but I want to loop

[R] Reformatting dataframe for use with icc()

Hello, I want to determine the inter-rater reliability of ratings made from a random selection of observers and observations. I plan to use the irr package to calculate the ICC, however, my dataframe is not organized in a way that the icc() function can handle. The icc() function works with

[R] NaNs produced running icc()

Hello, I want to determine the inter-rater reliability of ratings made from a random selection of 11 raters and 71 subjects using the irr package. Each rater was randomly assigned to rater only a handful of subjects. So there will be some cells with NAs for raters who did not rate a particular

[R] Is it possible to extract coefficient '(Intercept)' with an identifier (Group ID)

Hello, I have a data set with 80 observations (21 groups) on which I have run an MLM (using lme). I want to extract the coefficients for the intercept from my MLM using: coefficients(summary(mig1.mlm))$'(Intercept)' This produces a list of 21 intercepts, one for each group. For another test I
