scale_x_continuous : Discrete value supplied to continuous scale - r
I'm a beginner in R. I get this error
Error: Discrete value supplied to continuous scale
when I try to use
scale_x_continuous(breaks=1:10)
The plot I get is the following one. As you can see, the axis needs to be reduced...
I get my data from a csv file
dput(head(Data, 20))

At first, I though it was a problem with class of variables (numeric, factor...) but even when I convert to numeric it doesnt work...
Data$Pmanche <- levels(Data$Pmanche)[Data$Pmanche]
Data$Pcsge <- levels(Data$Pcsge)[Data$Pcsge]
Thanks for your time!

p<- ggplot(Data, aes(Pmanche,Pcsge))
p + geom_point() + scale_x_continuous(breaks=1:10)
Ok, I solved it.
The problem was the data source.
I learned we need to be careful when taking data from excel... Decimals must be indicated with "." and not ","
Thanks

The next row of the data starts a new period and so on. I want to group the rows by the periods that exist in the data.
Although the code provided in this example can find the periods if fully completed data is provided (it worked for the first three periods), when applied to the entire dataset of periodic data, it resulted in NaNs.
ssp <- spectrum(DATA$Rotation, plot = FALSE, method = "ar", n.freq = 1e6)
period <- 1 / with(ssp, freq[spec == max(spec)])
DATA$Loop <- (seq_len(nrow(DATA)) %/% period) + 1
Here's an approach where I define a region where both the Rotation is increasing and Rotation is at least as high as the starting value. Then I count how many times we enter that region and that's the period number. library(dplyr) Rot_start = DATA$Rotation[1] rbind(DATA, DATA) %>% # to demonstrate two cycles mutate(Rot_pos = Rotation > lag(Rotation, default = -1), Rot_rightside = Rotation >= Rot_start, Rot_region = Rot_pos & Rot_rightside, new_period = Rot_region & !(lag(Rot_region, default = FALSE)), period = cumsum(new_period)) # more succinct, same workings # mutate(Rot_region = Rotation > lag(Rotation, default = -1) & Rotation >= Rot_start, # period = cumsum(Rot_region & !(lag(Rot_region, default = FALSE))))

But doing this recreate the row numbers. Is there any simple function to combine while keeping the row names intact? Thanks!
These lines of code should solve the problem z0 <- as.numeric(c(rownames(cc), rownames(ccc))) z <- data.frame(c(cc$c, ccc$b)) row.names(z) <- z0 data.frame(z[order(as.numeric(row.names(z))),])
Doing curve fitting in R for a power series
I have trying to estimate the annual of an investment scheme which applied dollar cost averaging, which the increment of value is listed as below (sorry that MathJax looks like greek to me, so I didn't use it):
x: regular contribution, which is 1500 in my case
y: rate of return PLUS 100% (e.g 1.07 for a 7% return), which is the parameters that I want to estimate.
Time 1: xy
Time 2: (x + xy)*y
Time 3: (x + (x + xy)*y)*y
Time 4: (x + (x + (x + xy)*y)*y)*y
Time 5: (x + (x + (x + (x + xy)*y)*y)*y)*y
Time 6: (x + (x + (x + (x + (x + xy)*y)*y)*y)*y)*y
And the list goes on.
After simplifying the equation, if I calculate it correctly, it should be a power series:
xy(1 + y + y^2 + y^3 + y^4 + y^5 +y^6)
I know that equation above can be used for the nls function in R, as suggested in http://www.walkingrandomly.com/?p=5254. But the problem is, the investment scheme has been traded for more than 6 times, the number of trades is variable and I prefer not to fix the number of trades in the formula.
I wonder if R can create a formula with variable length of the power series, something like a function?

Computing angle between two vectors (with one vector having a specific X,Y position)
I am trying to compute the angle between two vectors, wherein one vector is fixed and the other vector is constantly moving. I already know the math in this and I found a code before:
theta <- acos( sum(a*b) / ( sqrt(sum(a * a)) * sqrt(sum(b * b)) ) )
I tried defining my a as:
a<-c(503,391)
and my b as:
b <- NM[, c("X","Y")]
When I apply the theta function I get:
Warning message:
In acos(sum(a * b)/(sqrt(sum(a * a)) * sqrt(sum(b * b)))) : NaNs produced
I would appreciate help to solve this.
And here is my sample data:
structure(list(A = structure(c(1L, 1L, 1L, 1L, 1L, 1L), .Label =

Your function is not vectorized. Try this:
theta <- function(x,Y) apply(Y,1,function(y,x) acos( sum(x*y) / ( sqrt(sum(x^2)) * sqrt(sum(y^2)) ) ),x=x)
a<-c(503,391)
b <- DF[, c("X","Y")]
theta(a,b)
# 1 2 3 4 5 6
#0.6412264 0.6412264 0.6412264 0.6412264 0.6412264 0.6412264
There is a problem with the acos and atan functions in this application, as you cannot compute angles for the full circle, only for the plus quadrant. In 2D, you need two values to specify a vector, and you need two values (sin and cos) to define it in degrees/radians up to 2pi. Here is an example of the acos problem: plot(seq(1,10,pi/20)) ## A sequence of numbers plot(cos(seq(1,10,pi/20))) ## Their cosines plot(acos(cos(seq(1,10,pi/20)))) ## NOT Back to the original sequence Here's an idea: angle <- circular::coord2rad(x, y) plot(angle) where "(x,y)" has "angle" as.numeric(angle) gives the angle in radians (0,360). To report geographical directions, convert to degrees, and other things, you can use the added parameters for the circular function, e.g.: x <- coord2rad(ea,eo, control.circular = list(type = "directions",units = "degrees")) plot(x) as.numeric(x)
