What is wrong with the following?
x<- 1:2
if(x[1]> 0)
{
if(x[2]> 0)
{
print("1& 2> 0")
}
else
{
print("1> 0")

}
else
{
if(x[2]> 0)

else
{

}
Gives me
Error: unexpected 'else' in "else"
What am I missing?

x <- 1:2
#this works
if (x[1] > 0)
{ if (x[2] > 0) print("1 & 2 > 0") else print("1 > 0") } else
{ if (x[2] > 0) print("2 > 0") else print("NONE > 0") }

else print("1 > 0") } else
{ if (x[2] > 0) print("2 > 0")
else print("NONE > 0") }
#this doesn't
if (x[1] > 0)
{ if (x[2] > 0) print("1 & 2 > 0")
else print("1 > 0") }
else { if (x[2] > 0) print("2 > 0") else print("NONE > 0") }
Conclusion: if-else in R is not quite free-form.
