When I tried to run the library(semPlot) , always receive an error message:

library(semPlot) Error: package or namespace load failed for ‘semPlot’: objeto ‘readPNG’ não foi exportado por 'namespace:png'

Besides when I run the function sem Paths another error :

Error in semPaths(fit, title = FALSE, sizeMan = 4, sizeMan2 = 4, sizeLat = 4, : could not find function "semPaths"

Could someone help me?

I resolved this problem as follows:

  1. Install semPlot using install.packages("semPlot")
  2. Wait for the dependencies to install
  3. Restart R
  4. Invoke the install command again using install.packages("semPlot")

I found that this installed two remaining libraries (XML and semPlot) and I was able to continue my analysis.
