could please tell me switch in r returns second argument if true , third if false? i have searched switch , if else function , have looked through documentation when using ubiquitous terms if , else seems hard identify solution. i looking like: f(true,1,2); f(false,1,2) [1] 1 [1] 2 i working on reading through documentation of julia has made me aware of of gaps in knowledge in r. in julia there operator available. (true ? 1 : 2) 1 (false ? 1 : 2) 2 simply ifelse ifelse(true,1,2) ## [1] 1 ifelse(false,1,2) ## [1] 2

perlin explained in pseudo-code: http://freespace.virgin.net/hugo.elias/models/m_perlin.htm the tutorial gives me random number generator function writen in pseudo-code. returns floating number in range of (-1, 1). function intnoise(32-bit integer: x) x = (x<<13) ^ x; return ( 1.0 - ( (x * (x * x * 15731 + 789221) + 1376312589) & 7fffffff) / 1073741824.0); end intnoise function so if function returns number in range (-1, 1), can't use random.uniform(-1, 1) ? meet problem: function noise(x) . . end function function smoothnoise_1d(x) return noise(x)/2 + noise(x-1)/4 + noise(x+1)/4 end function i guess noise(x) function generates random numbers 1d noise. i can't seem understand x parameter is. seed? and, can't use random.uniform(-1, 1) the noise function used in perlin noise seeded random number generator. is, must return same value every time called same value parameter, x . can think of x position in

i building restful api retrieving , storing comments in threads. a comment thread identified arbitrary uri -- url of web page comment thread related to. design similar disqus uses system. this way, on every web page, querying related comment thread doesn't require storing additional data @ client -- needed canonical url page in question. my current implementation attempts make uri work resource encoding uri string follows: /comments/https%3a%2f%2fexample.org%2ffoo%2f2345%3ffoo%3dbar%26baz%3dxyz however, before dispatching application, request uri gets decoded server /comments/https://example.org/foo/2345?foo=bar&baz=xyz this isn't working because decoded resource name has path delimiters , query string in causing routing in api confused (my routing configuration assumes request path contains /comments/ followed string). i double-encode them or using other encoding scheme uri encode, add complexity clients, i'm trying avoid. i have 2 specific quest

i need place label @ right, above of fitted average horizontal rule. have y-coordinate of rule, don't know coordinate of right border of graph. i saw, use at graph 0.5,0.8 syntax, if horizontal rule fixed, isn't. you can use different coordinate systems x , y values. available coordinate systems are: first : value on left , bottom axes. second : value on right , top axes. graph : relative area within axes, 0,0 bottom left , 1,1 top right. screen : relative entire canvas. character : depends on chosen font size. so, if x-value should relative graph, use graph 0.5 , y-value can use first yval : set label @ graph 0.5, first yval+ofs here, yval y-value of horizontal line, , ofs offset in order displace label bit.
