ifelse() and missing values in test conditions
R experts,
I have been unable to get the following ifelse statement to work as desired when applied
to my data frame.
Example:
DF$ANYEF <- with(DF,ifelse(PSOUGHT1=='ANY'|PSOUGHT2=='ANY'|PSOUGHT3=='ANY',PEFF,0))
##### this statement will be replicated 16 times for 16 unique _EF variables ###
Basically, I want each ANYEF for each row to equal the corresponding row value for column
PEFF if 'ANY' occurs at least once among columns PSOUGHT1, PSOUGHT2, and PSOUGHT3, and I want
ANYEF to equal 0...

monorepo: bad performance when using gitk / git log

I've mainly seen it when using gitk on specific files/directories, but since gitk seems to be using "git log --no-color -z --pretty=raw --show-notes --parents --boundary HEAD -- <file>" it
