Returns scatter plot with regression results

1 2	plotreg(x, y, dat, titl, xlab, ylab, scx, scy, w, names, sepa, ini, font, logs, cv, nx, ny, stepx, stepy)

`x`	string with name of variable on x axis
`y`	string with name of variable on y axis
`dat`	data frame with data
`titl`	string with tittle
`xlab`	string with lable x axis, x by default
`ylab`	string with lable y axisa, y by default
`scx`	scale x variable. E.g 10s,100s, 1000s,... scx=1 by default
`scy`	scale y variable. E.g 10s,100s, 1000s,... scy=1 by default
`w`	string with name of regression weights variable. Equal weight by default
`names`	string with name of data points labels. E.g. City, State, Country
`sepa`	parameter used to calibrate the frequency tick marks, large values imply lower frequency. sepa=0 produces one label per data point
`ini`	number beyond which the frequency of names is reduced
`font`	plot font, serif by default
`logs`	use of logs in the regression, logs=0 y~x, logs=1: log(y)~log(x), logs=2: log(y)~x, logs=3: y~log(x)
`cv`	name of covariates
`nx`	horizontal adjustment for data points labels
`ny`	vertical adjustment for data points labels
