Hi R users,
I still have the problem about plotting. I wanted to put the datasets on
one figure, x-axis represents values B, y-axis represents values C, while
different colors label column A. Each record uses a circle on the figure,
while hollow circles represent DF=1 and solid circles represent D
I see the problem on Windows 10, R-3.4.0, R.exe. It is not compiled for
debugging but gdb gives some information when I attach the debugger after
the 'R..has stopped working' popup appears. I don't know how reliable it
is:
(gdb) info threads
Id Target Id Frame
* 4Thread 11848.0x1
I am not able to reproduce your segfault on a Windows 7 platform either:
##
fn1 <- "d:/DADOS_ENEM_2009.txt"
sessionInfo()
## R version 3.4.1 (2017-06-30)
## Platform: x86_64-w64-mingw32/x64 (64-bit)
## Running under: Windows 7 x64 (build 7601) Service Pack 1
##
## Matrix p
...
and here is a slightly cleaner and more transparent way of doing the
same thing (setdiff() does the matching)
> with(df, setdiff(ID,ID[samples %in% c("B","C") ]))

I am not able to reproduce this on a Linux platform:

## Platform: x86_64-pc-linux-gnu (64-bit)
## Running under: Ubuntu 14.04.5 LTS

If I understand correctly, no looping (ave(), for()) or type casting
(as.character()) is needed -- indexing and matching suffice:
> with(df, ID[!ID %in% unique(ID[samples %in% c("B","C") ])])
[1] 3 3

Dear All,
wonder if you could please assist with the following
df<-data.frame(ID=c(1,1,1,2,2,3,3,4,4,5,5),samples=c("A","B","C","A","C","A","D","C","B","A","C"))
from this data frame the goal is to extract the value of 3 from the ID column
based on the logic that the ID=3 in the data frame has
hi, thanks Dr. Murdoch
i'd appreciate if anyone on r-help could help me narrow this down? i
believe the segfault occurs because there's a single line with 4GB and also
embedded nuls, but i am not sure how to artificially construct that?
the lodown package can be removed from my example.. it i

Segfaults are usually worth reporting as bugs. Try to come up with a
