I am attempting to add a calculated column to a data frame. Basically, adding a column called "newcol2" which are the stock closing prices from 1 day to the next. The one little hang up is the name of the column. There seems to be an additional data column name included in the attributes (dimnames?). So when i run HEAD(DATAFRAMENAME) i get the column name = "Open". but

Hi, I have been using CentOS 7 on a laptop for a while now (about two years), using skypeforlinux all the time. After today's update, skype ceased to start as a service, as it used to be configured. It fails to start manually, e.g., it does start and is listed as a job, but it doesn't appear visible on the desktop. In the case you know something about it, please let us all know.

Hi, I'm not in the list and I just would like to comment it to the comunity. So, if someone want to contact me, make CC to me in the reply. The wiki page [1] talk about networking, and show two typical configurations: "virtual network" and "shared physical device". The shared physical device has an error or something that could make confused, I think. What I want to

Hello,   I would like to create a function that computes intraday returns of a financial asset on a calendar time basis, without making any loop. For instance, I want to get price returns every 60 seconds. The main problem is that the times series of prices is irregularly spaced in time. I have looked in the "zoo" or "its" classes but have not found any answer to my problem.

Hi, You may need to add "dec=","" in the read.csv. dat1<- read.table(text=" Time;Mid 31/01/2013 00:00;1,35679 31/01/2013 00:01;1,35678 31/01/2013 00:02;1,356785 31/01/2013 00:03;1,35689 31/01/2013 00:04;1,3569 31/01/2013 00:05;1,3569 31/01/2013 00:06;1,356885 31/01/2013 00:07;1,35691 31/01/2013 00:08;1,357

Hi Everyone. I am downloading intraday Bloomberg data from R.

Hi, I have an intraday timeseries of financial data (see below) which has gaps due to market opening and closing hours. I am trying to plot it, but the time gap is always visible in the plot. I tried converting data to xts, zoo, timeSeries and plotting it with different functions i.e. plot.xts, plot.zoo. The only way to make it work was with function 'chartSeries' in the quantmod package

If the connection is not local, paths of disks will refer to the remote host, which were mistakenly handled as local paths (in the best case failing to open a non-existing disk, and in the worst case opening a different disk!). In case the disks are remote resources like ssh or ceph, nothing guarantees that the hostname can be reached from the local machine, or even that it is actually the same on

Hi, I have typical situation, local LAN with private addresses, translated via NAT to internet.
