Are there any functions available to calculate sunrise and sunset times for given latitude,longitude and dates? If not, I'll appreciatte any pointers to C code I could use/port. Thanks, Angel

##This is a function that I am trying to write to calculate sunrise and sunset and works "mostly", but returns nonsensical values. What am I #missing? Thanks in advance. ###remember to include maptools as dependence### library(maptools) sunrise.set <- function(lat, long, date, timezone="UTC", num.days=1){ #this needs to be long lat# lat.long <- matrix(c(long, lat),

# I am sure that I could be more efficient than this but how? Thanks in advance. #GPS in Decimal Degrees in the form longitude latitude RM215 <- matrix(c(-82.1461363, 33.5959109), nrow=1) SC <- matrix(c(-82.025888, 33.606454), nrow=1) RM202 <- matrix(c(-81.9906723, 33.5027653), nrow=1) RM198 <- matrix(c(-81.926823, 33.4634678), nrow=1) HC <- matrix(c(-81.920505, 33.46192), nrow=1)

Hello to all, I have two dataframes, the first with two columns sunrise and sunset (for 10 years). Each of these columns is formatted for date time (ex: 01-Jan-2010 15:37:00) In the second data frame I have GPS information and also a date time column (same format ). What I would like to do is a subset of all the rows from the second dataframe that occurred in day time only so between sunrise

Hi We have two subnets with routing tables correctly set up so they can both ping to our Sun Solaris Box. 193.71.221 191.9.211 The Sun Solaris box lives on 193.71.221.1 and all PCs on that subnet can map to the Sun box without any problems. All PCs on the 191.9.211 cannot connect to the samba drives giving the error "Network not Found". Any help would be much appreciated. Thanks

I have looked at ?as.POSIXct ?POSIXct and many of the references that are on those pages. I am bewildered with timezones. Is there a way to get what would go into tz="" for making a function that uses POSIXct to be able to be used in all of the timezones in just the united states? This is for both windows and mac... this is the function that I am wanting to use it with

Hi Leon, I don't have the infra (nor the knowledge or expertise) to create a LiveCD I didn't think about Fedora. This is indeed a good pointer, I will definitely try that Actually, I'm not too worried about the basics, but rather about the wifi, audio & video drivers (one of the boxes is a multimedia system) Thanks!

I am sure someone must have come across this. Is it possible to force files to binary when copying to Unix directories. NT -> Unix. Text Files have got ^M in them. How do we prevent this happening. Would forcing to binary fix the problem & if so how would this be done? Thanks Ajmal Ajmal Rafique eCommerce +44(0)1384 445564 (Telephone) +44(0)1384 446838 (Fax)

Hi, I have a data.frame that contains a variable act which records the duration (in seconds) of two states (wet-dry) for several individuals (identified by Ring) over a period of time. Since I want to work with daytime (i.e. from sunrise till sunset) and night time (i.e. from sunset till next sunrise), I have to split act from time[i] till sunset and from sunset until time[i+1], and from time[k]

For those driving c++11 in clang/llvm - Would it generally be acceptable to have a "sunrise" period where the preliminary evaluation has been done (buildbots, compiler evaluate.. etc) and the 1st actual c++11 commit hits the repo. (30-60 days?) ------------- My concern/thoughts - When we swap out STDCXX for libc++ - We aren't able to self host clang. This could be entirely *our*

Hello, I've caught a glimpse of the new RHEL 6.5 (well, new packages landed in CentOS) and I notice it now provides quite a nice version of Gluster 3.4.0 with a lot of backports. I've got 2 problems now: - I've got gluster installed from http://download.gluster.org/pub/gluster/glusterfs/3.4/3.4.0/CentOS/epel-6/x86_64/, but the package in EL6 Base will not upgrade it nicely

Hi I had asked for some help with the Asterisk Assistants http://www.voip-info.org/tiki-index.php?page=Asterisk+Assistants+for+MacOSX and many have offered assistance with translations which I am grateful for and like to say thank you again. However, there hasn't been a single response from a graphic designer to offer help with a custom icon. Are there any graphic designers on this list at

Dear R helpers, I have a dataframe (test1) containing the time of sunrise and sunset for each day of the year for 3 years. I have another dataframe (test2) containing measurements that are taken every 15 minutes, 24/7. I would like to extract all rows from test2 that occur between sunrise and sunset for the appropriate date. Can you suggest a good vectorized way to do this? Keep in mind

Does anyone know if there is a sunrise sunset calculator for R? -- Let's not spend our time and resources thinking about things that are so little or so large that all they really do for us is puff us up and make us feel like gods.

Great stuff. Please, can you share your adjustments to the Makefiles with the community?! If you don't
