installation error (Failed to install 'Ularcirc' from GitHub)

[silvermoon8902]

Dear Sir or Madam,

I am trying to use the Ularcirc to visualize the circRNAs I found. I just followed the installation pipeline but failed with the error info:

package ‘yaml’ successfully unpacked and MD5 sums checked
Error: Failed to install 'Ularcirc' from GitHub:
(converted from warning) cannot remove prior installation of package ‘yaml’

Do you know how to resolve the issue?

thanks,

Shan

Hi Shan,

It appears as if the yaml library may not have updated as message says cannot remove prior installation. Can you cehck what version of yaml is installed, this can be done easily through RStudio or the following R command line.

p <- installed.packages()
p[which(p[,1] == "yaml"),1:3]

you may need to delete yaml directly before attempting to re-install. To do this navigate to the folder/directory identified by p[which(p[,1] == "yaml"),2] and remove it. Then start the Ularcirc installation again.

Cheers,
D
