Hi all,
I have a data frame for which I want to limit the output by checking whether
row values for specific column meets particular conditions.
Here are the more specific details:
I have a function that checks whether an input string exists in a defined
list:-
checkBaseLine <- function(s){
for (listItem in WHITELIST){
if(regexpr(as.character(listItem), s)[1] > -1){
return(TRUE)
}
}
return(FALSE)
}
Now, I have a data frame for which I want to apply the above function for
all row values for a given column:-
This works fine when I define a condition like:
data <- data[data$urlType != 1,]
However, I want to combine two logical conditions together like:
data <- data[data$urlType != 1 & checkBaseLine(data$url),]
This would check whether the column `urlType` contains row values that !=
1,
and the column `url` contains row values that gets evaluated using the
defined function.
Any ideas how this can be done?
Thanks in advance.
Regards,
Harsh Yadav
