Hi,

I. Important issues:
-----------------------------
[1] Spinboxes for negative numbers is buggy. Scrolling down below 0 goes like 
this: 0, -0.01, -1e+10, -2e+10 ... This effects all the plugins where a 
spinbox allows a negative number.

[2] Scrolling up is generally fine, unless starting from -0.01, in which case 
it shoots to 1e+10. This effects all plugins where spinboxes allow both 
negative and positive (real) numbes.

[3] Exponential quantiles: input box not being evaluated. Some problem with 
the variable.

[4] Binomial quantile/probab: Call to undefined function clealup??? Plugin 
error.

M. Minor issues:
-------------------
[1] In the quantiles/probabilities plugins, make the input box (of 
quantiles/probabilites) as required. ie., disable the "Submit" when the box 
is empty. As of now, there is an error of rk.temp being not found.

[2] Beta quantiles and probabilities: bound "ncp" parameter below by 0 and 
default to 0.

[3] F quantile: add ncp

[4] Gamma quantiles/probab: bound Rate below by 0.01 and set it default to 1.

[5] Logistic quantile/probab: Scale should be bounded below by 0 (0.01) and 
not 1.

[6] Lognormal quantiles/probab: bound sdlog below by 0.01.

[7] Normal quantiles/probab: bound sd below by 0.01.

[8] t quantile/probab: add ncp.

[9] Tukey quantile/probab: Sample size should be bounded below by 1

[10] Uniform quantile/probab: "Lower limits of the distribution" default to 0. 
And may be change the name to Minimum/Maximum to be consistent with R.

[11] Weibull quantile/probab: Scale should be bounded below by 0 (0.01) and 1.

[12] Neg-Binom quantiles/probab: Trials has to be integer. And default probab 
say 0.5, not 1.

[13] Neg-Binom plot: Trials has to be integer.

[14] Possion quantile/probab: bound lambda below by 0.

[15] Wilcoxon quantile/probab: label for n has "s" missing from "econd". Both 
m and n can be bounded below by 1 instead of 0.

C. Cosmetic issues:
----------------------------
[1] Should new line be accepted in input boxes? (like, main, sub, xlabel 
etc..)
[2] In quantile/probabilities plugin, enter 0.50.095 (no space!) in the input 
box. Put the cursor between, 0.5 and 0.95 and hit Enter ie provide a newline. 
This causes an error.
[3] plot_beta_distribution.rkh: remove the link to plot_beta_distribution.
[4] For all plot_*_distribution.rkh: remove the "standrard distribution" line.

I will take care of C[3] and C[4] and send a diff file soon.

D. Wish?
-------------
By default, any plugin shows only two lines of code, and to see the rest of 
the code, The window has to dragged longer and the internal divider adjusted 
to see the rest/all of the code. Is it anyway possible to show more than two 
lines of code by default?

Regards
PK.
