I am trying condition handling and recovery for the first time in R. I want to use read.zoo
function in a loop to read a number of csv files with two different time formats, say format 1 and format 2. So obviously when I am using format1 in read.zoo to read a csv file in which times are in format 2 then it would give me an error, so I want to bypass that error message and want to try the format 2 inside read.zoo
function. I am trying something like,
my.zoo <- tryCatch(expr = read.zoo(my.csv, format = format1),
error = read.zoo(my.csv, format = format2)
But I am always getting the error message about the time format regardless of time format. I am not sure if I am using the tryCatch
function properly or if there is any other way to do it. Any help is appreciated. Thanks in advance.

The recovery has to be wrapped into the error
function in order for tryCatch
to operate properly, you can try something like this instead:
my.zoo = tryCatch(
expr = read.zoo(my.csv, format = format1),
error = function(e) read.zoo(my.csv, format = format2)
)
