Working with R, I was looking for functionality to easily subset my data based on a sequence of numbers. After writing a for loop and using
rbind to do it initially (terrible to do in R!), I finally found a way to do this efficiently. Using a command called
%in%, you can easily apply it as a filter in the
subset command to get data filtered based on your sequence. Enjoy!
# Generate sample data based to test. sample_data <- data.frame(ID=seq(1,100,1), Score=sample(0:100,100,rep=TRUE)) summary(sample_data) # Plot the scores, see that there is a score for each id. plot(sample_data$Score~sample_data$ID) # Create a filter to apply. look_at <- seq(1,100,10) # Filter the sample data by look_at using the %in% command. subset_data <- subset(sample_data, ID %in% look_at) # Plot the scores, note the filtered data. plot(subset_data$Score~subset_data$ID)
