plot confidence intervals as shaded band
Hi,
does anyone know how do I plot confidence intervals as a shaded band around a curve, rather than as errors bars?
many thanks,
ulisses.

confidence interval as shaded band (lme)
Hi all,
I?m trying to plot confidence intervals for the fitted values I get with my
lme model in R.
Is there any way I can plot this in the form of a shaded band, like the
output of geom_smooth() in ggplot2 package. ggplot2 seems to use only lm,
glm, gam, loess and rlm as smoothing methods.
Any advice on the functions I should use to accomplish this will be very
helpful.
Thank you very much.

how to draw confidence interval lines of a fitted curve of polynominal regression
Hello,
I drew a plot of weight and height of people and fitted it with a
polynominal regression x^2.
(using curve())
Now I would like to draw the confidence interval line for the fitted curve.
Please kindly advise the code for the purpose.
Thank you.

Help with pair plot
Hi,
I'm trying to create a plot using pair.

Confidence Inteval for regression curve.
Dear all,
I have a dataset which I need to estimate the regression model and plot the estimated curve two other curves with low and high confidence interval (CI=95%). How can I do that?
x<-1:100
y<-x^0.2+rnorm(100,0.1,0.1)
mod<-glm(y~log(x))
plot(y~x)
lines(predict(mod)~x,col=2)
Kind regards,

ggplot2: goem_smooth and suppress messages
Hi
When I run my script using ggplot and geom_smooth I get messages that I
would like to suppress:
p <- ggplot(dataSubset)
p <- p + aes(x = as.Date(factor(key),format="%Y%m%d")) + geom_line()
p <- p + geom_smooth(span=0.2,se=FALSE,size=0.7)
The messages look like this:

ggplot2: geom_smooth and legend
Hi all,
Is that possible to remove the grey colour in the legend key that goes
with the geom_smooth? In my case it doesn't ease the reading of the
legend.

Newbie: Drawing fitted lines on subset of data
Hello,
I's still working with my tsibble of weight data for the last 20 years.
In addition to drawing an overall trend line, using lm, for the whole
data set, I'd like to draw short lines that would recompute lm and draw
it, say, just for the years from 2010:2015.
Here's a short example that I think illustrates what I'm trying to do.

back-transform predictors for x-axis in plot -- mgcv package
My question is related to plot( ) in the mgcv package. Before modelling
the data, a few predictors were transformed to normalize them.
Therefore, the x-axes in the plots show transformed predictor values.
How do I back-transform the predictors so that the plots are easier to
interpret?
Thanks in advance,

Zooming in to a ggplot (a sort of ylim, but ylim won't do)
Dear Helpers,
I wonder whether you might be able to help me. I have a plot composed of
ggplot (and a follow on geom_smooth call). I would like to restrict the
display range of the y axis to a smaller range, a sort of zooming onto a
region. I attempted to use ylim, but it will effect the range (i.e. effect
the geom_smooth call). Is there any way that I can save the results up to
geom_smooth call

ggplot2 - regression statistics how to display on plot
Hello -
So I am trying to use ggplot2 to show a linear regression between two variables, but I want to also show the fit of the line on the graph as well.
I am using ggplot2 for other graphics in what I am working on, so even though this would be a fairly easy thing to do in Excel, I would prefer to do it in R to keep my look and feel, and I think ggplot2 is just cooler.
Here is a sample
