I got the error message: "package ‘titletoc’ is not available (for R version 3.6.0)" but I checked MiKTeX Console that the package "titlesec" is in the list of packages and all the packages are updates. I am using a Mac (not sure if it matters).
Then I searched online to try to install the package "titletoc" separately, but I found nowhere to download this package. Something must be wrong, anyone has a clue?
I needed to install the R package quadprog, which only works for R with version 3.6.0. So I installed R (3.6.0 version), and open it with RStudio. But now I failed to load any libraries, even after I installed the packages successfully using install.packages("package_name"). Specifically, the libraries I need to load are caret, forecast and ggplot2. I tried re-installing R but it still does not work. The error message I get is
Error: package or namespace load failed for ‘forecast’ in
dyn.load(file, DLLpath = DLLpath, ...): unable to load shared object
'/Library/Frameworks/R.framework/Versions/3.6/Resources/library/Rcpp/libs/Rcpp.so':

After installing Rcpp package successfully with install.packages("Rcpp") , I still got the message above when I tried library(Rcpp). So I am completely stumbled here...(before upgrades, everything works fine except I cannot install quadprog, so cannot install forecast package as well). Can anyone please help me fix this issue?
Please see below the images showing that the packages are stored in the same directory path of the R.
I read that you need to recompile your old packages after upgrading to newer version of R. Run the following line in your R terminal
update.packages(ask=FALSE,
checkBuilt=TRUE,
repos="https://cloud.r-project.org")
Then
install.packages(c("Rcpp", "caret", "forecast", "ggplot2", "quadprog"),
dependencies=TRUE,
repos="https://cloud.r-project.org")
Had similar issue, restart R session and install Rcpp from source
install.packages("Rcpp", type="source")
then load the library
library(Rcpp)
if still getting the error, restart R session and try loading library again.
I ended up by getting and then google searching the exact error code :). I fixed it by installing the latest version of R from CRAN along with the latest version of Rstudio. What I think happened was that when I updated some packages R and Rstudio were out of sync.
Yesterday I tried to open a R Markdown in Rstudio. Rstudio forced me to download something, Now everytime I restart Rstudio or install package, it shows
Error in loadNamespace(name) : there is no package called ‘yaml’
Error in loadNamespace(name) : there is no package called ‘yaml’"
I saw someone say that I can resolve this by removing all packages I have installed, but I only found the remove.package function, which can only remove one package at a time.
If I want to delete all packages, what should I do?
(I use Mac)
Having some issues helping a colleague at work install RStudio. She was getting the following error message whenever she opened up the programme and when trying to install new packages.
Error in yaml.load(readLines(con), error.label = error.label, ...) :
object 'C_unserialize_from_yaml' not found
Error in yaml.load(readLines(con), error.label = error.label, ...) :
object 'C_unserialize_from_yaml' not found
Seems to be the error that's being discussed here. We've followed the steps in the answers and haven't had any luck.
Uninstalled the yaml package, reinstalled RStudio and got a different error message (not surprising given the package was no longer installed).
Error in loadNamespace(name) : there is no package called ‘yaml’
Error in loadNamespace(name) : there is no package called ‘yaml’
Then tried each of the answers in the link and ended up with the original error message again.
Beyond what I've googled in the past 15 minutes, I don't know anything about yaml or what it's supposed to do. Opening R rather than RStudio seems to work as it should.
R version is 3.4.3, RStudio is 1.1.423 for Windows and yaml version that was originally installed was 2.1.16. Not sure if it's relevant, but we are on work laptops that require us to install new programmes (and in the case of R, packages) into C:\Users\NAME\Desktop\My Software, but that seems to have been done correctly.
Any help greatly appreciated.
Thanks,
James
Im a bit new to R and need to use/adapt someone else code in R.
My supervisor uses R version 3.2.2 with the dplyr package version 0.4.3 (to overcome errors and problems with the original code).
I tried to install the older dplyr package with different methods:
- installed devtools package and then used the url devtools::install_url("http://cran.r-project.org/src/contrib/Archive/dplyr/dplyr_0.1.2.tar.gz")
- manual installation (where I downloaded the file and tried to install it.) Installation seemed to have worked but when I run the code it gives a fatal error massage
Every way I've tried so far either gives a lot of error messages or a fatal error and shutdown.
When using help ?dplyr it gives a pop-up that there is an error. Does anybody have any other ideas to install this package?
Thanks!
