How to plot multiple graphs each with multiple y variables
I am new to R and have a problem that I haven't been able to find the answer to in the guides or online. I have multiple datasets, D1, D2, D3, D4, D5, D6, D7 and D8, and I would like to produce two plots side by side using mfrow.  The first plot should contain data from D1-D4, the second should contain D5-D8. I can plot these separately using the code, par(mfrow=c(1,1)) plot(c(0.000001,1),c(0,100),type="n", xlab="D", yl...

Rounding variables in a data frame
Hi All I am trying to use the round function on some columns of a dataframe while leaving others unchanged. I wish to specify those columns to leave unchanged. My attempt is below - here, I would like the column d3 to be left but columns d1, d2 and d4 to be rounded to 0 decimal places. I would welcome any suggestions for a nicer way of doing this. d1= rnorm(10,10) d2= rnorm(10,6) d3= rnorm(10,2) d4= rnorm(10,-4) d = data.frame(d1,d2,d3,d4) x= NULL for (i in 1:ncol(d)){ if (colnames(d)[i] =="d3"){x[i] = d[i] } else { x[i] = roun...

D4 AMI - No Caller ID
I currently have Asterisk deployed in my office with a TE411P. On the first port of this card is a T1 from the telco setup for D4 AMI. Unfortunately, I'm not receiving caller ID on inbound calls from this line. The caller ID information is arriving in the form *ANI*DNIS*. In zapata.conf, I have signalling set to em_w. The DNIS always arrives correctly, but I'm never receiving the ANI for caller ID. I'm starti...
