Hi, This might be me missing something painfully obvious but why does the cube root of the following produce an NaN? > (-4)^(1/3) [1] NaN > As we can see: > (-1.587401)^3 [1] -4 Thanks! Greg

Hi ?atan2 says that atan2(y,x)=atan(y/x) for x and y numeric or complex vectors. Well, I would expect atan2(1,1i) to be equal to atan(-1i), but > atan2(1,1i) Error in atan2(y, x) : Non-numeric argument to mathematical function > R.version _ platform powerpc-apple-darwin8.5.0 arch powerpc os darwin8.5.0 system powerpc, darwin8.5.0

I need help writing function that takes three categorical inputs and returns a vector of summary statistics based on these inputs. The data set contains information on retail goods that can be specified by their retail segment, brand name, and type of good along with its retail price and what it actually sold for. I need to write a function that will take these inputs and average, count, and

Hello, I am trying to read a database exported from SAS. It is form of csv, and the date format reads '02-Feb-99'. I used following code to convert character to date format, db$dob<-as.Date(db$dob, format="%d-%b-%y"). but it doesn't work, only seems NA. What's wrong with this code? Thank you in advance. Best, Dong-Hee Koh [[alternative HTML version deleted]]

Thank you for providing the example code... for the request of running it multiple times it would have helped if you could have confirmed that the example ran through without errors... there were a lot of mistakes in it. Look into using the reprex package to check your example next time. I don't do this kind of analysis... I really don't know what to expect from the functions. The

The laws already exist: Disturbing the peace, Misappropriation of public funds, Prohibition on unfunded mandates. What's lacking is prosecutors, judges, and juries who see the politicians as getting in the way of the statesmen and the people. To drag this back towards On Topic, it seems to me that the ntp folks might be petitioned to write up and submit to the Congress, a paper

with kvm and virtio- would -m 1024 take proceedence over -balloon virtio? when i use both together, i see memory stay around 1024 MB less on my host side. I know the guest is not taking but a fraction of that ram, so I would expect the virtio balloon to take the majority of the guests ram and hand it back to the host. this is using the free util/command to take snapshots of the host memory.?

There has been a recent thread on R-help on this, which resurrected concepts from bug reports PR#1228 and PR#6743. Since the discussion has included a lot of erroneous 'information' based on misunderstandings of floating-point computations, this is an attempt to set the record straight and explain the solutions adopted. The problem was that var(rep(0.02, 10)) was observed to be (on

I am regularly running into a problem where I can't seem to figure out how maintain correct data order when selecting data out of a dataframe. The below code shows an example of trying to pull data from a dataframe using ordered zip codes. My problem is returning the pulled data in the correct order. This is a very simple example, but it illustrates a regular problem that I am running into.

I read the following in acinclude.m4: ## R_PROG_CC_FLAG_D__NO_MATH_INLINES ## --------------------------- ## In current glibc, inline version [x86] of exp is broken. ## We fix this by adding '-D__NO_MATH_INLINES' to R_XTRA_CFLAGS rather ## than AC_DEFINE(__NO_MATH_INLINES) as the former also takes care of ## compiling C code for add-on packages. Is this documented anywhere (where?), e.g.

Can someone please enlighten me as to why the following happens? > -2.7^8.6 [1] -5125.407 > p<- -2.7 > q<- 8.6 > p^q [1] NaN R seems perfectly able to calculate -2.7^8.6, but fails when the exact same values are assigned to variables and then the computation is repeated. Thanks in advance for any suggetsions. Kris.

Hello, I've discovered homer-api-postgresql and homer-api-mysql packages in Stretch repo. I'm not sure I understand how Homer-API relates to Homer. My questions are: 1. What is the simplest available installation option to install Homer on a dedicated box, this dedicated box gathering data from one or several Asterisk systems on the same LAN ? 2. Is it possible to centralize data on a
