converting histogram to barchart
Hi list,
After a lot of tweaking i have managed to create a histogram with an
overlaying density plot. The histogram shows a sample of birth weights
of babies and the density plot shows birth weights from a much larger
reference populaton. My data is divided in 0.1 Kg bins so in the code
below binweigh=0.1.
The trouble with the current graph is that it is not very clear since
the density plot

Need ideas on how to show spikes in my data and how to code it in R
Hi
I have recently been analyzing birthweight data from a clinic. The
data has obvious defects in that there is digit preference on certain
weights making them overrepresented. This shows as spikes in the
histogram on certain well rounded weights like 2, 2.5, 3, etc. I
would like to show this to government officials but can't figure out
how I should present the finding in an easy to

Finding proportion of observations that are outliers from the left tail of the normal distribution
Hi fellow users
I have a new R problem i am hoping to get some pointers on. I have a
dataset that is approximately normally distributed but with a fat left
tail. I am interested in a good measurement on how much fatter the
left tail is than can be expected from a normal distribution. One
thing I'll tried was fitting a two component mixture model with the
Rmix package but i am also interested

Adjusting for heaping in data
Hi R users. I am new to the community and have got myself into a little problem.
I have a dataset of birth weights recorded by nurses at a delivery
clinic in an developing country.
The weights are entered in KiloGrams with one decimal. However there
is substantial heaping at each 500g when looking at the sample in a
histogram. Do anyone of you know a easy way to adjust for this and if
it exists
