I have a series of animals that are being radio-tracked. I have written some code that goes through each animal and calculates the total distance that each animal is traveling. I will need to run these data on a regular basis and want to write the result to a .php webpage file so that the page updates automatically when I re-run the code. I thought I'd be able to use the "writeLines" command, but this only works for character strings. In addition, it doesn't seem to allow me to insert the distance traveled value where I want it (update Distance where ID=2829, for example). Does anyone know of a command that I could write a value to a specific location in .php code? I simply need to read a particular line in my .php code, then insert my distance value into a field value that currently has the value ' ' as a space holder. My code is currently:
# Loop through dataset, summarizing data based on Animal name wild_ID <-unique(wild$ID) Animal <-unique(wild$Name) filepath <-"c:/Jared/Data/Kenya/Wildebeest/Summary/" # Create an empty dataframe dat3 <- data.frame(Animal) for (i in c(1:length(wild_ID))) { # Create Subset dat <-subset(wild, ID == wild_ID[i]) # Calculate Sum of Movement, put in km dat2 <-(sum(dat$STEPLENGTH))/1000 dat3$Distance[i] <-dat2 # Write Value to CSV file outfile <-paste(filepath,"Animal_Distances",".csv",sep="") write.csv(dat3,file=outfile, quote = FALSE, row.names = FALSE) # Create PHP connection and export distance traveled to specific location in PHP code PHP <-file(description = "x:/Web/Gnu/tracking_copy_temp.php", open = "r+") ###### This is the part that doesn't work.####### # Write dat3 value to correct line in code, need where statement writeLines(dat3$Distance, con = PHP) # Close PHP connection close(PHP) } Thanks in advance for any suggestions.
