One (dirty) way to do it is to use tryCatch with an empty function for error handling. For example, the following code raises an error and breaks the loop :
for (i in 1:10) {
print(i)
if (i==7) stop("Urgh, the iphone is in the blender !")
}
[1] 1
[1] 2
[1] 3
[1] 4
[1] 5
[1] 6
[1] 7
Erreur : Urgh, the iphone is in the blender !
But you can wrap your instructions into a tryCatch with an error handling function that does nothing, for example :
for (i in 1:10) {
tryCatch({
print(i)
if (i==7) stop("Urgh, the iphone is in the blender !")
}, error=function(e){})
}
[1] 1
[1] 2
[1] 3
[1] 4
[1] 5
[1] 6
[1] 7
[1] 8
[1] 9
[1] 10
But I think you should at least print the error message to know if something bad happened while letting your code continue to run :
for (i in 1:10) {
tryCatch({
print(i)
if (i==7) stop("Urgh, the iphone is in the blender !")
}, error=function(e){cat("ERROR :",conditionMessage(e), "\n")})
}
[1] 1
[1] 2
[1] 3
[1] 4
[1] 5
[1] 6
[1] 7
ERROR : Urgh, the iphone is in the blender !
[1] 8
[1] 9
[1] 10
EDIT : So to apply tryCatch in your case would be something like :
for (v in 2:180){
tryCatch({
mypath=file.path("C:", "file1", (paste("graph",names(mydata[columnname]), ".pdf", sep="-")))
pdf(file=mypath)
mytitle = paste("anything")
myplotfunction(mydata[,columnnumber]) ## this function is defined previously in the program
dev.off()
}, error=function(e){cat("ERROR :",conditionMessage(e), "\n")})
}
