What makes you think this is a bug in R?
Whenever I try changing a function, it keeps coming up with the same
error
message.
I have the function
CN_state_log_sum=function(Tot_log_sum){ #estimate copy number state
for the log
[...]
}
When I try to run it in the loop:
for (j in 1:length(BB_mean_ref)){ # find copy number states (0 for
homozygous
deletion, 1 for hemizygous deletion, 2 for neutral, 3 for single
amplification,
4 for multiple amplification)
state_log_sum[j]=CN_state_log_sum(Tot_log_sum[j])
state_sum_log[j]=CN_state_sum_log(Tot_sum_log[j])
}
I get the error message:
Error in Im(Tot_sum_log) != 0 || Re(Tot_sum_log) <- 2 :
could not find function "||<-"
The error message indicates that the problem happens in the function
CN_state_sum_log() rather than CN_state_log_sum(), so it's hardly
surprising that changing the latter doesn't have any effect.
My guess: you've go a condition (Re(Tot_sum_log)<-2), which is
mistaken for the assignment operator "<-" by the R parser. Adding some
whitespace (Re(Tot_sum_log) < -2) should help both R and human readers
to make sense of it.
Best,
Stefan
