"RLANG" error in lavaan CFA

[Agnieszka Ewa Łyś]

Hi, I am trying to perform a CFA. I am using a script from previous year and this script worked perfectly a year ago but now something has changed- I have seen several times a statement "there is no package called 'rlang'" which is strange because there is no such a package mentioned in the script. This error occurs also when I am trying to import dataset thus R does not show any results of CFA because it doesn't see the data. Do you have any idea how to deal with this problem?

rlang is a package that you can install. 

install.packages(“rlang”)

library(“rlang”)

However, as far as I know, lavaan doesn’t depend on this package. So this isn’t a lavaan problem but R. 

Something else in your r script does (tidyverse stuff? tibbles? dplyr?)

Thank you for your replies. I have tried to install the "rlang" but the error still occurs. The syntax is:

setwd("C:/Users/CEM/Documents/wielość Ja/art skala pluralizmu/wyniki.sav")
library(sjPlot)
library(probemod)
library(lavaan)
library(jtools)
library(mediation)
library(broom)
library(QuantPsyc)
library(processr)
library(foreign)
library(ggplot2)
#install.packages("effects")
library(effects)
#install.packages("aod")
library(aod)
library(graphics)
#install.packages("ResourceSelection")
library(ResourceSelection)
#install.packages("pROC")

install.packages("semPlot")
library("semPlot")

'
bootstrap=1000L
fit<-cfa(SPS.CFA,data=results,estimator="MLR")
summary(fit,fit.measures=TRUE)

and the error is:

Error: package or namespace load failed for ‘semPlot’ in loadNamespace(j <- i[[1L]], c(lib.loc, .libPaths()), versionCheck = vI[[j]]): there is no package called 'rlang'

and:

  object 'results' not found

When I am trying to import the data from SPSS the statement  "there is no package called 'rlang'" appears again.

This line:

Error: package or namespace load failed for ‘semPlot’ in loadNamespace(j  <- i[[1L]], c(lib.loc, .libPaths()), versionCheck = vI[[j]]): there  is no package called 'rlang'

means rlang has not been installed. What happens when you just type:

install.packages("rlang")
library(rlang)

Make sure to close R before you run this commands and then reopen R.

Also you can read in data with foreign instead of haven

spss.dat <- foreign::read.spss("name_of_dataset.sav", to.data.frame = TRUE)

I have no idea why lack of "rlang" was a problem but I installed "rlang" and now it's ok. Thank you!
