Hi,
Try:
x$Log <- gsub("^(\\d{2})(\\d{2})\\.(\\d{3})","\\1:\\2:\\3E",sprintf("%.3f",x$Log))
x$lat <- gsub("^(\\d{1})(\\d{2})\\.(\\d{3})","\\1:\\2:\\3S",sprintf("%.3f",x$lat))
x
# Log lat
#1 30:25:264E 9:01:331S
#2 30:39:237E 8:10:811S
#3 31:37:760E 8:06:040S
#4 31:41:190E 8:06:557S
#5 31:41:229E 8:06:622S
#6 31:38:891E 8:06:281S

3138.891 806.281",
header=TRUE,
stringsAsFactors=FALSE)
I what to insert “:” after every first
two numbers in Lon variable and after
every first number in lat variable.
The variables should end with “E” for
Lon and “S” for the Lon variable. The
results should look like:
Lon Lat
30:25:264E 9:01:331S
30:39:237E 8:10:811S
31:37:760E 8:06:040S
31:41:190E 8:06:557S
31:41:229E 8:06:622S
31:38:891E 8:06:281S
I am using gmt package for
geocodes conversion.
I will appreciate any help.
