4 months ago I continue here - for the complex keyboard: c) In the complex keyboard the keys need to change slightly and the tooltips need to be added.
Here is the current keyboard:
1) The complex key provides as.complex(). I suggest it is for the complex command instead and we have a second key with label as.complex as well. So the top keys become:
complex, as.complex, real, imaginary
2) Then the second row could become:
mod, arg, conjugate, rad
3) The third becomes:
sin, cos, tan, deg
4) The 4th row of keys:
sinh, cosh, tanh, exp
5) And the last full row:
sqrt, roun d, signif, log
6) A 6th short row, before the R help, with 2 keys:
i , pi
7) The key withi, just gives the letter i. And the key with pi, should not include the brackets. It is currently pi( ) and it just becomes pi.
I still have tooltips to add:
complex: Tooltip Construct a complex number. For example complex(3, 2) gives 3 + 2i.
as.complex: Tooltip Define a variable as complex. For example as.complex(-1) gives 1 + 0i
real: Tooltip The real part of a complex number. For example Re(3 + 2i) gives 3.
imaginary: Tooltip The imaginary part of a complex number or variable. For example Im(3 + 2i) gives 2.
New second row:
mod: Tooltip The modulus (polar coordinate) of a complex number or variable. For example Mod(3 + 2i) gives 3.606, which is sqrt(33 + 22). Also abs(3 + 2i) is the same as Mod(3 + 2i).
arg: Tooltip The argument (polar coordinate) of a complex number or variable. For example Arg(3 + 2i) gives 0.588 where 3 = 3.606cos(0.588) and 2 = 3.606sin(0.588).
conjugate: Tooltip Conjugate of a complex number or variable: For example Conj(3 + 2i) gives 3 - 2i.
rad: Tooltip Change from degrees to radians. For example rad(90 + 180i) gives (1.571 + 3.142i)
deg: Tooltip Change from radians to degrees. For example deg(pi/2 + 3.142i) gives (90 + 180i)
sqrt: Tooltip Square root. For example sqrt(-9 + 0i) gives (0 + 3i) or just 3i. sqrt(-9 + 2i) gives 0.331 + 3.018i)
exp: The exponential function. For example exp(3 + 2i) gives
round: Tooltip round(pi/2 + 3.14259i) gives 2 + 3i) so rounds to whole numbers. round(pi/2 + 3.14259i, 2) gives 1.57 + 3.14i, so rounds to 2 decimals.
signif: Rounds to give the specified number off digits in the larger of the components. For example signif(0.424 + 511.38i, 3) gives (0 + 511i)
@N-thony I suggest this is a good @Fidel365 task, if you agree? It is essentially item d) in the issue #8877 where he has completed a) to c) already.
The
maths keyboardis incomplete in the tooltips. I had not noticed this earleir. They are suggested below a) Also the R Help is for the stats package. Please addbaseas well. Make it the first, thenstatsand also add thecarandcircularpackages. b) The missing tooltips are suggested as follows: deg: Tooltip: Change for radians to degrees. For example deg(pi/2) = 90. exp: Tooltip: The exponential function. exp(1) = e = 2.71828. exp(0) = 1, exp(-2) = 0.1353 = 1/exp(2). It is the inverse of the log function, so exp(6.238) = 512, while log(512) = 6.238. abs: Tooltip: The absolute (or positive) value. For example abs (-4.4) = abs(4.4) = 4.4. sign: Tooltip: The sign of the corresponding values. So sign(4.2)=1, sign(-20)=-1, sign(c(-2,-1,0,1,2,3))= (-1,-1,0,1,1,1) logit: Tooltip: log(p/(1-p)) for p between 0 and 1, or between 0 and 100 if you have percentages. For example logit(c(0.2, 0.5, 0.95)) is (-1.386, 0, 2.944). logistic: Tooltip: Distribution function for the logistic distribution. For example dlogis(c(-2,-1,0,1,2), 0, 5513) = (0.026, 0.14, 0.5, 0.86, 0.974). The scale of 0.5513 gives a standard deviation of 1.atan2: atan2(x,y) gives the angle between the x axis and the vector between to origin and the point (x,y). For example atan2(1,1) = 0.7854 = pi/4 (=45 degrees).
c) In the complex keyboard the keys need to change slightly and the tooltips need to be added.
