se's and CI's for fitted lines in multivariate regression analysis
I?m entirely stumped on this particular issue and really hoping someone has
some advice for me.
I am running a covariant model in lm I would like to give the standard
errors or the confidence intervals for the fitted lines. I?ve been using the
dataset OrangeSprays where I want lines for each level of treatment over the
covariant ?colpos?. I?ve been able to calculate intercepts and slopes for

grey colored lines and overwriting labels i qqplot2
I created this graph in ggplot and added ablines to the different facets by
specifying with subset commands. As you might see, there are still a few
issues.
1.) I would like to have the diamonds in a grey scale instead of colors. I
accomplished this (see graph 2) until I overwrote the label title for the
treatments and the colors came back (graph 1). I used these two commands:
p=ggplot(data =

changing graphs in qqplot2
This is what I have now so far.

nesting scale_manual caracteristics in ggplot
Hi there,
I am having a little problem with combining three scale_manual commands in a
facet plot. I am not able to combine the three different characteristics,
instead ending up with three different descriptions next to the graph for
the same geom. I would like to see two separate labels (not three); one
describing lines 1-7 and the other 8-14. For each of the treatments (A-B) I
want a

Side by side scatter plots with specified regression lines
I am new and self taught in R, so please bear with me.
I want to create two scatter plots side by side. The data set includes
measurements from two different countries with 7 treatments over a timeline
(x-axis).
Problem 1
I want to have each plot to include the data from one of the countries with
7 regression lines of the treatments, but I do no know how to divide the
data between them. This is
